From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  PATENT, PRUSSIAN. This subject will be considered by taking a view of the 
  persons who may obtain patents; the nature of the patent; and the duration 
  of the right. 
       2.-Sec. 1, Of the persons who may obtain patents. Prussian citizens 
  or subjects are alone entitled to a patent. Foreigners can not obtain one. 
       3.-Sec. 2. Nature of the patents. Patents are granted in Prussia for 
  an invention when the thing has been discovered or invented by the 
  applicant. For an improvement, when considerable improvement has been made 
  to a thing before known. And for importation, when the thing has been 
  brought from a foreign country and put in use in the kingdom. Patents may 
  extend over the whole country or only over a particular part. 
       4.-Sec. 3. Duration of patents. The patent may at the choice of the 
  applicant, be for any period not less than six months nor more than fifteen 
  years. 
  
  

From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  PATENT, ROMAN. The Roman patents will be considered by taking a view of the 
  persons to whom they may be granted; the different kinds of patents; the 
  cost of a patent; and the obligations of the patentee. 
       2.-Sec. 1. To whom patents are granted. Every person, whether a 
  citizen of the estates of the pope or foreigner, man or woman, adult or 
  infant, may obtain a patent for an invention, for an improvement, or for 
  importation, by fulfilling the conditions prescribed in order to obtain a 
  grant of such titles. Persons who have received a patent from the Roman 
  government may, afterwards, without any compromise of their rights or 
  privileges, receive a patent in a foreign country. 
       3. The different kinds of patents. In the Roman estates there are 
  granted patents for invention, for improvements, and for importations. 
       4.-1st. Patents for inventions are granted for, 1. A new kind of 
  important culture. 2. A new and useful art, before unknown. 3. A new and 
  useful process of culture or of manufacture. 4. A new natural production. 5. 
  A new application of a means already, known. 
       5.-2d. Patents for improvements may be granted for any useful 
  improvement made to inventions already known and used in the Roman states. 
       6.-3d, Patents for importations are granted in two cases, namely: 1. 
  For the introduction of inventions already patented in a foreign country, 
  and the privilege of which patent yet continues. 2. For the introduction of 
  an invention known and freely used in a foreign country, but not yet used or 
  known in the Roman states. 
       7.-3. Cost of a patent. The cost of a patent is fixed at a certain 
  sum per annum, without regard to the length of time for which it may have 
  been granted. It varies in relation to patents for inventions and 
  importation. It is ten Roman crowns per annum for a patent for invention and 
  improvement, and of fifteen crowns a year for a patent for importation. 
       8.-Sec. 4. Obligation of the patentee. He is required to bring into 
  [?] his invention within one year after the grant of the patent, and not to 
  suspend the supply for the space of one year during the time the privilege 
  shall last. 
       9. He is required to pay one half of the tax or expense of his patent 
  on receiving his patent, and the other half during the first month of the 
  second portion of its, duration. 
  
  

From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  PATENT, construction. That which is open or manifest.
       2. This word is usually applied to ambiguities which are said to be 
  latent, or patent. 
       3. A patent ambiguity is one which is produced by the uncertainty, 
  contradictoriness or deficiency of the language of an instrument, so that no 
  discovery of facts or proof of declaration can restore the doubtful or 
  smothered sense without adding ideas which the actual words will not of 
  themselves sustain. Bac. Max. 99 T. Raym. R. 411; Roberts on Fr. 15. 
       4. A latent ambiguity may be explained by parol evidence, but the rule 
  is, different with regard to a patent ambiguity, which cannot be explained 
  by parol proof. The following instance has been proposed by the court as a 
  patent ambiguity: "If A B, by deed, give goods to one of the sons of J S, 
  who has several sons, he shall not aver which was intended; for by judgment 
  of law upon this deed, the gift is void for uncertainty, which cannot be 
  supplied by averment." 8 Co. 155 a. And no difference exists between a deed 
  and a will upon this subject. 2 Atk. 239. 
       5. This rule, which allows an explanation of latent ambiguities, and 
  which forbids the use of parol evidence to explain a patent ambiguity, is 
  difficult of application. It is attended, in some instances, with very 
  minute nicety of discrimination, and becomes a little unsteady in its 
  application. When a bequest is made "to Jones, son of, Jones," or "to Mrs. 
  B," it is not easy to show that the ambiguity which this imperfect 
  designation creates, is not ambiguity arising upon the face of the will, and 
  as such, an ambiguity patent, yet parol evidence is admitted to ascertain 
  the persons intended by those ambiguous terms. 
       6. The principle upon which parol testimony is admitted in these cases, 
  is probably, in the first of them, a presumption of possible ignorance in 
  the testator of the christian name of the legatee; and in the second, a 
  similar presumption of his being in the habit of calling the person by the 
  name of Mrs. B. Presumptions, which being raised upon the face of the will, 
  may be confirmed and explained by extrinsic evidence. Rob' on. Fr. 15, 27; 2 
  Vern. 624, 5; 1 Vern. by Raithby, 31, note 2; 1 Rop. Leg. 147; 3 Stark. Ev. 
  1000; 3 Bro. C. C. 311 2 Atk. 239; 3 Atk. 257; 3 Ves. Jr. 547. Vide articles 
  Ambiguity; Latent. 
  
  

From Bouvier's Law Dictionary, Revised 6th Ed (1856) :

  PATENT, contracts. A patent for an invention is a giant made by the 
  government of the United States to the inventor of any new or useful art, 
  machine, manufacture or composition of matter, or any new and useful 
  improvement in any art, machine, manufacture or composition of matter not 
  known or used by others before his or their discovery or invention thereof, 
  and not, at the time of his application for a patent, in public use or on 
  sale, with his consent or allowance, as the inventor or discoverer; securing 
  to him for a limited time, therein expressed, the full and exclusive right 
  and liberty of making, constructing, using, and vending to others to be 
  used, the said invention or discovery, on certain conditions, among which is 
  the one of at once giving up his secret and making public his discovery or 
  invention, and the manner of making and using the same, so that at the 
  expiration of his privilege, it may become public property. The instrument 
  securing this grant is also called a patent. The subject will be considered 
  by taking a succinct view of, 1. The legislation of the United States on the 
  subject. 2. The patentee. 3. The subject to be patented. 4. The caveat and 
  preliminary proceedings. 5. The proceedings to obtain a patent. 6. The 
  patent. 7. The duty or tax on patents. 8. Courts having jurisdiction in 
  patent cases. 9. Actions for violations of patents. Sec. 1. Legislation of 
  the United States. 
       2. The constitution of the United States authorizes congress to pass 
  laws "to, promote the progress of science and the useful arts, by securing, 
  for limited times, to authors and inventors, the exclusive right of their 
  respective writings and discoveries." Art. 1, s. 8, n. 8. By virtue of this 
  authority congress can grant patents to inventors, and it rests in the 
  sound, discretion of the legislature to say when, and for what length of 
  time, and under what circumstances the patent for an invention shall be 
  granted. Congress may, therefore, grant a patent which shall operate 
  retrospectively by securing to the inventor the use of his invention, though 
  it was in public use and enjoyed by the community at the time this act was 
  passed. 3 Sumn. 535; 2 Story, R. 164. The first act passed under this power 
  is that which established the patent office on the 10th of April, 1790, 1 
  Story, L. U. S. 80. There were several supplements and modifications to this 
  first law, namely, the acts passed February 7, 1793, Idem, 300; June 7, 
  1794, Idem, 363; April 17, 1800, Idem, 753; July 3,1832, 4 Sharsw. cont. of 
  Story, L. U.S. 2300; July 13, 1832, Idem, 2313. 
       3. These acts were repealed by the act of July 4, 1836, 4 Sharsw. cont. 
  Story, L. U. S. 2504, which. enacts: 
       Sec. 21. That all acts and parts of acts theretofore passed on this 
  subject be, and the same are hereby repealed: Provided, however, That all 
  actions and processes, in law or equity sued out prior to the passage of 
  this act, may be prosecuted to final judgment and execution, in the same 
  manner as though this act had not been passed, excepting and saving the 
  application to any such action, of the provisions of the fourteenth and 
  fifteenth sections of this act, so far as they maybe applicable thereto. And 
  provided, also, That all applications and petitions for patents, pending at 
  the time of the passage of this act, in cases where the duty has been paid, 
  shall be proceeded with and acted on in the same manner as though filed 
  after the passage thereof. 
       4. The existing laws on the subject of patents are the act of July 4, 
  1836, already mentioned; the acts of March 3, 1837; Idem, 2546; March 3, 
  1839; 9 Laws U. S, 1019; August29,1842; ch. 263, Pamph. Laws, 171; May 27, 
  1848. Minot's Stat. at Large, U. S. 231. Sec. 2. Of the patentee. 
       5. Any person or persons having discovered or invented the thing to be 
  patented, whether he be a citizen of the United States or an alien, is 
  entitled to a patent on fulfilling the requirements of the law. Act of July 
  4, 1836, s. 6. 
       6. By the 10th section of the same act it is provided, That where any 
  person hath made, or shall have made, any new invention, discovery or 
  improvement, on account of which a patent might by virtue of this act be 
  granted, and, such person shall die before any patent shall be granted 
  therefor, the right of applying for and obtaining such patent shall devolve 
  on the executor or administrator of such person, in trust for the heirs at, 
  law of the deceased, in case he shall have died intestate; but if otherwise, 
  then in trust for his devisees, in as full and ample manner, and under the 
  same conditions, limitations, and restrictions, as the same was held, or 
  might have been claimed or enjoyed by such in his or her lifetime; and when 
  application for a patent shall be made by such legal representatives, the 
  oath or affirmation provided in the sixth section of this act, shall be so 
  varied as to be applicable to them. 
       7. And by the act of March 3, 1837, section 6, it is enacted, That any 
  patent hereafter to be issued, may be made and issued to the assignee or 
  assignees of the inventor or discoverer, the assignment thereof being first 
  entered of record, and the application therefor being duly made, and the 
  specifications duly sworn to by the inventor. And in all cases, hereafter, 
  the applicant for a patent shall be held to furnish duplicate drawings, 
  Whenever the case admits of drawings, one of which to be deposited in the 
  office, and the other to be annexed to the patent, and considered a part of 
  the specification. 
       Sec. 3. The subject to be patented 
       8. Patents are granted, 1. For inventions and discoveries. 2. For 
  importations. 1. Patents for inventions and discoveries. By the act, of July 
  4, 1836, sect. 6, it is enacted, that any person or persons having 
  discovered or invented any new and useful art, machine,, manufacture, or 
  composition of matter, or any new and useful improvement on any art, 
  machine, manufacture, or composition of matter, not known or used by others 
  before his or their discovery or invention thereof, and not, at the time of 
  his application for a patent, in public use or on sale, with his consent or 
  allowance, as the inventor or discoverer, and shall desire to obtain an 
  exclusive property therein, may make application in writing to the 
  commissioner of patents, expressing such desire, and the commissioner on due 
  proceedings had, may grant a patent therefor. 
       9. The thing to be patented must be an invention Or discovery; it must 
  be new and useful. 
      10.-1. The invention or discovery must be something which the inventor 
  has himself found out; some peculiar device or manner of producing any given 
  effect. A patent cannot, therefore, be taken out for the elementary 
  principles of motion, which philosophy and science have discovered, but only 
  for the manner of applying them. 1 Gallis. 478; 2 Gallis. 51. 
      11. A patent may be taken out for an improvement on a machine which is 
  known and used; 3 Wheat. 454; but a mere change of former proportions, will 
  not entitle a party to a patent. 1 Gallis. 438; 2 Gallis. 51. 
      12. It is provided by the act of July 4, 1836, s. 13, that whenever the 
  original patentee shall be desirous of adding the description and 
  specification of any new improvement of the original invention or discovery 
  which shall have been invented or discovered by him subsequent to the date 
  of his patent, he may, like proceedings being had in all respects as in the 
  case of original applications, and on the payment of fifteen dollars, as 
  hereinbefore provided, have the same annexed to the original description and 
  specification; and the commissioner shall certify, on the margin of such 
  annexed description and specification, the time of its being annexed and 
  recorded; and the same shall thereafter have the same effect in law, to all 
  intents and purposes as though it had been embraced in the original 
  description and specification. 
      13. And by the act of March 3, 1837, s. 8, that, whenever application 
  shall be made to the commissioner for any addition of a newly discovered 
  improvement to be made on an existing patent, or when ever a patent shall be 
  returned for correction, and re-issue, the specification of claim annexed to 
  every such patent shall be subject to revision and restriction, in the same 
  manner as are original applications for patents; the commissioner, shall not 
  add any such improvement to the patent in the one case, nor grant the re-
  issue in the other case, until the applicant shall have entered a 
  disclaimer, or altered his specification of claim in accordance with the 
  decision of the commissioner; and in all such cases the applicant, if 
  dissatisfied with such decision, shall have the same remedy and be entitled 
  to the benefit of the same privileges and proceedings as are provided by law 
  in the case of original applications for patents. 
      14.-2. The thing patented must be a new and useful invention, 
  discovery or improvement. 
      15. Among inventors, he who is first in time, has a right to the patent 
  for the invention. Pet. C. C. R. 394. 
      16. But by the act of March 3, 1839, sect. 7, it is provided, that every 
  person or corporation who has, or shill have, purchased or constructed any 
  newly invented machine, manufacture, or composition of matter, prior to the 
  application by the inventor or discoverer for a patent, shall be held to 
  possess the right to use, and vend to others to be used, the specific 
  machine, manufacture, or composition of matter so made or purchased, without 
  liability therefor to the inventor, or any other person interested in such 
  invention; and no patent shall be held to be invalid by reason of such 
  purchase, sale, or use, prior to the application for a patent as aforesaid, 
  except on proof of abandonment of such invention to the public; or that such 
  purchase, sale, or prior use has been for more than two years prior to such 
  application for a patent. 
      17. By the term useful invention is meant an invention which may be 
  applied to some beneficial use in society, in contradistinction to an 
  invention which is injurious to morals, to the health, or good order of 
  society. 1 Mason, C. C. R. 302; 4 Wash. C. C; R. 9. The term is also opposed 
  to that which is frivolous or mischievous. 1 Mason, C. C. R. 182; Renouard, 
  177; Perpigna, Man. des Inv. c. 2, s. 1, page 50. See 3 Car. & P. 502; 1 
  Pet. C. C. R. 480; 1 U. S. Law Journ. 563; 1 Paine, 203; 2 Kent, Com. 368, 
  Dr; Phillim. on Pat. c. 7, s. 14. 
      18. The act of August 29, 1842, sect, 3, provides that any citizen or 
  citizens, or alien or aliens, having resided, one year in the United States, 
  and taken the oath of his or their intention to become a citizen or 
  citizens, who by his, her, or their own industry, genius, efforts, and 
  expense, may have invented or produced any new and original design for a 
  manufacture, whether of metal, or other material or materials, or any new 
  and original design for the printing of woolen, silk, cotton, or other 
  fabrics, or any new and original design for a bust, statue, or has relief or 
  composition in alto or basso relievo, or any new and original impression or 
  ornament, or to be placed on any article of manufacture, the same being 
  formed in marble or other material, or any new and useful pattern, or print, 
  or picture, to be either worked into or worked on, or printed, or painted, 
  or cast, or otherwise fixed on, any article of manufacture, or any new and 
  original shape or configuration of ally article of manufacture not known or 
  used by others before his, her, or their invention or production thereof, 
  and prior to the time of his, her, or their application for a patent 
  therefor, and who shall desire or obtain an exclusive Property or right 
  therein to make, use, and sell and vend. the same, or copies of the same, to 
  others, by them, made, used, and sold, may make application in writing to 
  the commissioner of patents, expressing such desire, and the commissioner, 
  on due proceedings had, may grant a patent therefor, as in the case. now of 
  application for a patent: Provided, That the fee in such cases which by the 
  now existing laws would be required of the particular applicant shall be 
  one-half the sum, and that the duration of said patent shall be seven years, 
  and that all the regulations and provisions which now apply to the obtaining 
  or protection of patents not inconsistent with the provision's of this act, 
  shall apply to applications under this section. 
      2. Patents for importations. 
      19. It is enacted by the act of March 3, 1839, s. 6, that no person 
  shall be debarred from receiving a patent for any invention or discovery, as 
  provided in the act approved on the fourth day of July, one thousand eight 
  hundred and thirty-six, to which this is additional, by reason of the same 
  having been patented in, a foreign country, more than six months prior to 
  his application: Provided, That the same shall not have been introduced into 
  public and common use, in the United States, prior to the application for 
  such patent: And provided, also, That in all cages every such patent shall 
  be limited to the term of fourteen years from the date or publication of 
  such foreign letters-patent. 
      20. And by the act of July 4, 1836, s. 8, it is provided, that nothing 
  in this act contained shall be, construed to deprive an original and true 
  inventor of the right to a patent for his invention, by reason of his having 
  previously taken out letters-patent therefor in a foreign country, and the 
  same having been published at any time within six mouths next preceding the 
  filing of his specification and drawing. 
      4. Of the caveat and other preliminary, proceedings. 
      21. The act of July 4, 1836, s. 12, provides that any citizen of the 
  United States, or alien who have been resident in the United States one year 
  next preceding, and shall have made oath of his intention to become a 
  citizen thereof, who shall have invented any new art, machine, or 
  improvement thereof, and shall desire further time to mature the same, may, 
  on paying to the credit of the treasury, in manner as provided in the ninth 
  section of this act, the sum of twenty dollars, file in the patent office a 
  caveat, setting forth the design and purpose thereof, and its principal and 
  distinguishing characteristics, and praying protection of his right, till he 
  shall have matured his invention -- which sum of twenty dollars, in case the 
  person filing such caveat shall afterwards take out a patent for the 
  invention therein mentioned, shall be considered a part of the sum herein 
  required for the same. And such caveat shall be filed in the confidential 
  archives of the office, and preserved in secrecy. And if application shall 
  be made by any other person within one year from the time of filing such 
  caveat, for a patent of any invention with which it may in any respect 
  interfere, it shall be the duty of the commissioner to deposit the 
  description, specifications, drawings, and model, in the confidential 
  archives of the office, and to give notice, by mail, to the person filing 
  the caveat, of such application, who shall, within three months after 
  receiving the notice, if he would avail himself of the benefit of his caveat,
  
  file his description, specifications, drawings, and model: and if, in the 
  opinion of the commissioner, the specifications of claim interfere with each 
  other, like proceeding& may be had in all respects as are in this act 
  provided in the case of interfering applications: Provided, however, That no 
  opinion or decision of any board of examiners, under the provisions of this 
  act, shall preclude any person interested in favor of or against the 
  validity of any patent which has been or may hereafter be granted, from the 
  right to contest the same in any judicial court in any action in which its, 
  validity may come in question. 
      22. And the same act, s. 8, directs, that whenever, the applicant shall 
  request it, the patent shall take date from the time of the filing of the 
  specification and drawings, not however, exceeding six mouths prior to the 
  actual issuing of the patent; and on like request, and the payment of the 
  duty herein required, by any applicant, his specification and drawings shall 
  be filed in the secret archives of the office, until he shall furnish the 
  model and the patent be issued, not exceeding the term of one year, the 
  applicant being entitled to notice of interfering application. 
      Sec. 5. Of the proceedings to obtain a patent.
      23. This section will be divided by considering the proceedings when 
  there is no opposition, and when there are conflicting claims. 
      1. Proceedings without opposition 
      24. The sixth section of the act of July 4, 1836, directs, that before 
  any inventor shall receive a patent for any such new invention or discovery, 
  he shall deliver a written description of his invention or discovery, and of 
  the manner and process of making, constructing, using, and compounding the 
  same, in such full, clear, and exact terms, avoiding unnecessary prolixity, 
  as to enable any person skilled in the art or science to which it 
  appertains, or with which it is most nearly connected, to make, construct, 
  compound, and use the same; and in case of any machine, he shall fully 
  explain the principle and the several modes in which he has contemplated the 
  application of that principle or character by which it may be distinguished 
  from other inventions and shall particularly specify and point out the part, 
  improvement, or combination, which he claims as his own invention or 
  discovery. He shall, furthermore, accompany the whole with a drawing, or 
  drawings, and written references, where the nature of the case admits of 
  drawings, or with specimens of ingredients, and of the composition of 
  matter, sufficient in quantity for the purpose of experiment, where the 
  invention or discovery is of a composition of matter; which descriptions and 
  drawings, signed by the inventor and attested by two witnesses; shall be 
  filed in the patent office; and be shall, moreover, furnish a model of his 
  invention, in all cases which admit of a representation by model, of a 
  convenient size to exhibit advantageously its several parts. The applicant 
  shall also make oath or affirmation that he does verily believe that he is 
  the original and first inventor or discoverer of the art, machine, 
  composition, or improvement, for which he solicits a patent, and that he 
  does not know or believe that the same was ever known or used; and also of 
  what country he is a citizen; which oath or affirmation may, be made before 
  any person authorized by law to administer oaths. 
      25. The fourth section of the act of August 29, 1842, provides that the 
  oath required for applicants for patents, may be taken, when the applicant 
  is not, for the time being, residing in the United States, before any 
  minister plenipotentiary, charge d affaires; consul, or commercial agent, 
  holding a commission under the government of the United States, or before 
  any notary public of the country in which such applicant may be. 
      26. And the act of March 3, 1837, sect. 13, provides that in all cases 
  in which an oath is required by this act, or by the act to which this is 
  additional, if the person of whom it is required shall be conscientiously 
  scrupulous of taking an oath, affirmation may be substituted therefor. 
      27. The seventh section of the act of July 4, 1836, further enacts, that 
  on the filing of any such application, description, and specification, and 
  the payment of the duty hereinafter provided, the commissioner shall make or 
  cause to be made, an examination of the alleged new invention or discovery; 
  and if, on any such examination, it shall not appear to the commissioner 
  that the same had been invented or discovered by any other person in this 
  country prior to the alleged invention or discovery thereof by the 
  applicant, or that it had been patented or described in any printed 
  publication in this or any foreign country, or had been in public use or on 
  sale with the applicant's consent or allowance prior to the application, if 
  the commissioner shall deem it to be sufficiently useful and important, it 
  shall be his duty to issue a patent therefor. But whenever on such 
  examination it shall appear to the commissioner that the applicant wag not 
  the original and first inventor or discoverer thereof, or that any part of 
  that which is claimed as new had before been invented or discovered, or 
  patented, or described in any printed, publication in this or any foreign 
  country, as aforesaid, or that the description is defective and 
  insufficient, he shall notify the applicant thereof, giving him, briefly, 
  such information and, references as may be useful in judging of the 
  propriety of renewing his application, or of altering his specification to 
  embrace only that part of the invention or discovery which is new. In every 
  such case, if the applicant shall elect to withdraw his application, 
  relinquishing his claim to the model, he shall be entitled to receive back 
  twenty dollars part of the duty required by this act, on filing a notice in 
  writing of such election in the patent office, a copy of which, certified by 
  the commissioner, shall be a sufficient warrant to the treasurer for paying 
  back to said applicant the said sum of twenty dollars. But if the said 
  applicant in such case shall persist in his claim for a patent, with or 
  without any alteration of his specification, he shall be required to make 
  oath or affirmation anew in manner as aforesaid. And if the specification 
  and claim shall not have been so modified as in the opinion of the 
  commissioner, shall entitle the applicant to a patent, he may, on appeal, 
  and upon request in writing, have the decision of the board of examiners, to 
  be composed of three disinterested persons, who shall be appointed for that 
  purpose by the secretary of state, one of whom at least, to be selected, if 
  practicable and convenient, for his knowledge and skill in the particular 
  art, manufacture, or branch of science to which the alleged invention 
  appertains; who shall be under oath or affirmation for the faithful and 
  impartial performance of the duty imposed upon them by said appointment. 
  Said board shall be furnished with a certificate in writing, of the opinion 
  and decision of the commissioner, stating the particular grounds of his 
  objection, and the part or parts of the invention which he considers as not 
  entitled to be patented. And the same board shall give reasonable notice to 
  the applicant, as well as to the commissioner of the time and place of their 
  meeting; that they may have an opportunity of furnishing them with such 
  facts and evidence as they may deem necessary to. a just decision; and it 
  shall be the duty of the commissioner to furnish to the board of examiners 
  such information as he may possess relative to the matter under their 
  consideration. And on an examination and consideration of the matter by such 
  board, it shall be in their power, or of a majority of them, to reverse the 
  decision of the commissioner, either in whole or in part; and their opinion 
  being certified to the commissioner, he shall be governed thereby, in the 
  further proceedings to be had on such application: Provided, however, That 
  before a board shall be instituted in any such case, the applicant shall pay 
  to the credit of the treasury, as provided in the ninth section of this act, 
  (see 47,) the sum of twenty-five dollars, and each of said persons so 
  appointed shall be entitled to receive for his services in each case, a sum 
  not exceeding ten dollars, to be determined and paid by the commissioner out 
  of any moneys in his hands, which shall be in full compensation to, the 
  persons who may be so appointed, for their examination and certificate as 
  aforesaid. 
      28. By the twelfth section of the act of March 3, 1839, the commissioner 
  of patents is vested with power to make all such regulation's in respect to 
  the taking of evidence to be used in contested leases before him, as may be 
  just and reasonable and so much of the act of July 4, 1836, as provides for 
  a board of examiners, is thereby repealed. 
      29. And by the same act, sect. 11, it is provided, that in all cases 
  where an appeal is now. allowed by law from the decision of the commissioner 
  of patents to a board of examiners provided for in the seventh section of 
  the act to which this is additional, the party, instead thereof, shall have 
  a right to appeal to the chief justice of the district court of the United 
  States for the district of Columbia, by giving notice thereof to the 
  commissioner, and filing in the patent office, within such time as the 
  commissioner shall appoint, his reasons of appeal, specifically set forth in 
  writing, and also paying into the patent office, to the credit of the patent 
  fund, the sum of twenty-five dollars. And it shall be the. duty of said 
  chief justice, on petition, to hear and determine all such appeals, and to 
  revise such decisions in a summary manner, on the evidence produced before 
  the commissioner, at such early and convenient time as he may appoint, first 
  notifying the commissioner of the time and place of hearing, whose duty it 
  shall be to give notice thereof to all parties who appear to be interested 
  therein, in such manner as said judge shall prescribe. The commissioner 
  shall also lay before the said judge all the original papers and evidence in 
  the case, together with the grounds of his decision, fully set forth in 
  writing, touching all the points involved by the reasons of appeal, to which 
  the revision shall be confined. And at the request of any party interested, 
  or at the desire of the judge, the commissioner and the examiners in the 
  patent office, may be examined under oath, in explanation of the principles 
  of the machine, or other thing for which a patent, in such case, is prayed 
  for. And it shall be the duty of said judge after a hearing of any such 
  case, to return all the papers to the commissioner, with a certificate of 
  his proceedings and decision, which shall be entered of record in the patent 
  office; land such decision, so certified, shall govern the further 
  proceedings of the commissioner in such case, Provided, however, That no 
  opinion or decision of the judge in any such case, shall preclude any person 
  interested in favor or against the validity of any patent, which has been or 
  way hereafter be granted, from the right to contest the same in any judicial 
  court, in any action in which its validity may come in question. 
      2. When there are conflicting claims.
      30. It is enacted by the 8th section of the act of July 4, 1836, that 
  whenever an application shall be made for a patent, which, in the opinion of 
  the commissioner, would interfere with any other patent for which an 
  application may be pending, or with any unexpired patent which shall have 
  been granted, it shall be the duty of the commissioner to give notice 
  thereof to such applicants or patentees; as the case maybe; and if either 
  shall be dissatisfied with the decision of the commissioner on the question 
  of priority, right or invention, on a hearing thereof, he may appeal from 
  such decision, on the like terms and conditions as are provided in the 
  preceding section of this act and like proceedings, shall be had, to 
  determine which, or whether either of the applicants is entitled to receive 
  a patent as prayed for. 
      31. And by the 16th section of the same act, that whenever there shall 
  be two interfering patents, or whenever a patent on application shall have 
  been refused on an adverse decision of a board of examiners, on the ground 
  that the patent applied for would interfere with an unexpired patent 
  previously granted, any person interested in any such patent, either by 
  assignment or otherwise, in the one case, and any such applicant in the 
  other, may have remedy by bill in equity; and the court having cognizance 
  thereof, on notice to adverse parties and other due proceedings had, may 
  adjudge and declare either the patents void in whole or in part, or 
  inoperative and invalid in any particular part or portion of the United 
  States, according to the interest which the parties in such suit may possess 
  in the patent or the inventions patented, and may also adjudge that such 
  applicant is entitled, according to the principles and provisions of this 
  act, to have and receive a patent for his invention, as specified in his 
  claim, or for any part thereof, as the fact of priority of right or 
  invention shall in any such case be made to appear. And such adjudication, 
  if it be in favor of the right of such applicant, shall authorize the 
  Commissioner to issue such patent, on his filing a copy of the adjudication, 
  and otherwise complying with the requisitions of this act. Provided, 
  however, that no such judgment or adjudication shall affect the rights of 
  any persons except the parties to the action and those deriving title from 
  or under them subsequent to the rendition of such judgment. And the 
  commissioner is vested by the 12th section of the act of March 3, 1839, with 
  powers to make such rules and regulations in respect to the taking of 
  evidence to be used in contested cases before him, as may be just and 
  reasonable. 
      32. The act of March 3, 1839, section 10, provides, that the provisions 
  of the sixteenth section of the before recited act shall extend to all cases 
  where the patents are refused for any reason whatever, either by the 
  commissioner of patents or by the chief justice of the district of Columbia, 
  upon appeals from the decision of said commissioner, as well as where the 
  same shall have been refused on account of, or by reason of interference 
  with a previously existing patent; and in all cases where there is ne 
  opposing party, a copy of the bill shall be served upon the commissioner of 
  patents, when the whole of the expenses of the proceeding shall be paid by 
  the applicant, whether the final decision shall be in his favor or 
  otherwise. 
      Sec. 6. Of the patent.
      33. This section will be divided by considering, 1. The form of the 
  patent. 2. The correction of the patent. 3. The special provisions of the 
  acts of congress occasioned by the burning of the patent office. 4. The 
  disclaimer. 5. The assignment of patents. 6. The extension of the patent. 7. 
  The requisites to be observed after the granting of a patent to secure it. 
      1. Form of the patent.
      34. The patent is to be issued in the form prescribed by the act of 
  congress. The fifth section of the act of July 4, 1836, directs, that all 
  patents issuing from said office shall be issued in the name of the United 
  States, and under the seal of said office, and be signed by the secretary of 
  state, and countersigned by the commissioner of the said office, and shall 
  be recorded, together with the descriptions, specifications and drawings, in 
  the said office, in books to be kept for that purpose. Every such patent 
  shall contain a short description or title of the invention or discovery, 
  correctly indicating its nature and design, and in its terms grant to the 
  applicant or applicants, his or their heirs, administrators, executors or 
  assigns, for a term not exceeding fourteen years, the full and exclusive 
  right and liberty of making, using, and vending to others to be used, the 
  said invention or discovery, referring to the specifications for the 
  particulars thereof, a copy of which shall be annexed to the patent, 
  specifying what the patentee claims as his invention or discovery. It is 
  usually dated at the time of issuing it, but by a provision of the last 
  mentioned act, section 8, whenever the applicant shall request it, the 
  patent shall take date, from the time of filing, the specification and 
  drawings, not, however, exceeding six months prior to the actual issuing of 
  the patent. 
      2. Correction of patent. 
      35. It is provided by the thirteenth section of the act of July. 4, 
  1836, that whenever any patent which has heretofore been granted, or which 
  shall hereafter be granted, shall be inoperative or invalid, by reason of a 
  defective or insufficient description or specification, or by reason of the 
  patentee claiming in his specification as his own invention, more than he 
  had or shall have a right to claim as new; if the error has, or shall have 
  arisen b y inadvertency, accident or mistake, and without any fraudulent or 
  deceptive intention, it shall be lawful for the commissioner, upon the 
  surrender to him of such patent, and the payment of the further duty of 
  fifteen dollars, to cause a new patent to be issued to the said inventor, 
  for the same invention, for the residue of the period then unexpired for 
  which the original patent was granted, in accordance with the patentee's 
  corrected description and specification. And in the event of his death, or 
  any assignment by him made of the original patent, a similar right shall 
  vest in his executors, administrators, or assignees. And the patent, so 
  reissued, together with the corrected description and specification, shall 
  have the same effect and operation in law, on the trial of all actions, 
  hereafter commenced for causes subsequently accruing, as though the same had 
  been originally filed in such corrected form, before the issuing out of the 
  original patent. And whenever the original patentee shall be desirous of 
  adding the description and specification of any new improvement of the 
  original invention or discovery which shall have been invented or discovered 
  by him subsequent to the date of his patent, he may, like proceedings being 
  had in all respects as in the case of original applications, and on the 
  payment of fifteen dollars, as hereinbefore provided, have the same annexed 
  to the original description and specification; and, the commissioner shall 
  certify, on the margin of such annexed description and specification, the 
  time of its being annexed and recorded; and the same shall thereafter have 
  the same effect in law, to all intents and purposes, as though it had been 
  embraced in the original description and specification. 
      36. And it is enacted by the act of March 3, 1837, section 5, that, 
  whenever a patent shall be returned for correction and reissue under the 
  thirteenth section of the act to which this is additional, and the patentee 
  shall desire several patents to be issued for distinct and separate parts of 
  the thing patented, he shall first pay, in manner and in addition to the sum 
  provided by that act, the sum of thirty dollars for each additional patent 
  so to be issued; Provided, however, that no patent made prior to the 
  aforesaid fifteenth day of December, 1836, shall be corrected and reissued 
  until a duplicate of the model and drawing of the thing as originally 
  invented, verified by oath as shall be required by the commissioner, shall 
  be deposited in the patent office: Nor shall any addition of an improvement 
  be made to any patent heretofore granted, nor any new patent to be issued 
  for an improvement made in any machine, manufacture, or process, to the 
  original inventor, assignee or possessor, of a patent therefor, nor any 
  disclaimer be admitted to record, until a duplicate model and drawing of the 
  thing originally intended, verified as aforesaid, shall have been deposited 
  in the patent office, if the commissioner shall require the same; nor shall 
  any patent be granted for an invention, improvement, or discovery, the model 
  or drawing of which shall have been lost, until another model and drawing, 
  if required by the commissioner, shall, in like manner, be deposited in the 
  patent office: 
      37. And in all such cases, as well as in those which may arise under the 
  third section of this act, the question of compensation for such models and 
  drawings, shall be subject to the judgment and decision of the commissioners 
  provided for in the fourth section, under the same limitations and 
  restrictions as are therein prescribed. 
      3. Special provisions occasioned by the burning the patent office. 
      38. The act of March 3, 1837, was passed to remedy the inconveniences 
  arising from the burning of the patent office. It is enacted, 
      39.-Sect. 1. That any person who may be in possession of, or in any way 
  interested in, any patent for an invention, discovery, or improvement, 
  issued prior to the fifteenth day of December, in the year of our Lord one 
  thousand eight hundred and thirty-six, or in an assignment of any patent, or 
  interest therein, executed, and recorded prior to the said fifteenth day of 
  December, may, without charge, on presentation or transmission thereof to 
  the commissioner of patents, have the same recorded anew in the patent 
  office, together with the descriptions, specifications of claim and drawings 
  annexed or belonging to the same; and it shall be the duty of the 
  commissioner to cause the same, or any authenticated copy of the original 
  record, specification, or drawing which he may obtain, to be transcribed and 
  copied into books of record to be kept for that purpose; and wherever a 
  drawing was not originally annexed to the patent and referred to in the 
  specification and drawing produced as a delineation of the invention, being 
  verified by oath in such manner as the commissioner shall require, may be 
  transmitted and placed on file, or copied as aforesaid, together with the 
  certificate of the oath; or such drawings may be made in the office, under 
  the direction of the commissioner, in conformity with the specification. And 
  it shall be the duty of the commissioner to take such measures as may be 
  advised and determined by the board commissioners provided for by the fourth 
  section, of this act, to obtain the patents, specifications, and copies 
  aforesaid, for the purpose of being so transcribed and recorded. And it 
  shall be the duty of each of the several clerks of the judicial courts of 
  the United States, to transmit, as soon as may be, to the commissioner of 
  the patent office, a statement of all the authenticated copies of patents, 
  descriptions, specifications, and drawings of inventions and discoveries 
  made and executed prior to the aforesaid fifteenth day of December, which 
  may be found on the files of his office; and also to make out and transmit 
  to said commissioner for record as aforesaid, a certified copy of every such 
  patent, description, specification, or drawing, which shall be specially 
  required by such commissioner. 
      40.-Sect. 2. That copies of such record and drawings, certified by the 
  commissioner, or, in his absence, by the chief clerk, shall be prima facie 
  evidence of the particulars of the invention and of the patent granted 
  therefore, in any judicial court of the United States, in all cases where 
  copies of the original record or specification and drawings would be 
  evidence, without proof of the loss of such originals and no patent issued 
  therefor by the patentee or other person prior to the aforesaid, fifteenth 
  day of December, shall, after the first day of June next, be received in 
  evidence in, any of the said courts in behalf of the patentee or other 
  person who shall be in possession of the same, unless it shall have been so 
  recorded anew, and a drawing of the invention, if separate from the patent, 
  verified as, aforesaid, deposited in the patent office; nor shall any 
  written assignment of any such patent, executed and, recorded prior to the 
  said fifteenth day of December, be received in evidence in any of the said 
  courts in behalf of the assignee or other person in possession thereof, 
  until it shall have been so recorded anew. 
      41.-Sect. 3. That whenever it shall appear to the commissioner that any 
  patent was destroyed by the burning of the patent office building on the 
  aforesaid fifteenth day of December, or was otherwise lost prior thereto, it 
  shall be his duty, on application terested therein, to issue a new patent 
  for the same invention or discovery bearing the date of the original patent, 
  with his certificate thereon that it was made and issued pursuant to the 
  provisions of the third section of this act, and shall enter the same of 
  record: Provided, however, That before such patent shall be issued, the 
  applicant therefor shall deposit in the patent office a duplicate, as near 
  as may be, of the original model, drawings, and description, with 
  specification of the invention or discovery, verified by oath, as shall be 
  required by the commissioner; and such patent and copies of such drawings 
  and descriptions, duly certified, shall be admissible as evidence in any 
  judicial court of the United States, and shall protect the rights of the 
  patentee, his administrators, heirs and assigns, to the extent only in which 
  they would have been protected by the original patent and specification. 
      42. The act of August 29, 1842, sect. 2, extends the provisions of the 
  last section to patents granted prior to the said fifteenth day of December, 
  though they may have been lost subsequently; provided, however, the same 
  shall not have been recorded anew under the provisions of said act. 
      4. Of the disclaimer. 
      43. The act of March 3, 1837 sect. 7, authorizes any patentee who shall 
  have, through inadvertence, accident, or mistake, made his specification of 
  claim too broad, claiming more than that of which he was the original or 
  first inventor, some material and substantial part of the thing patented 
  being truly and justly his own, any such patentee, his administrators, 
  executors, and assigns, whether of the, whole or of a sectional interest 
  therein, may make disclaimer of such parts of the thing patented as the 
  disclaimant shall not claim to hold by virtue of the patent or assignment, 
  stating therein the extent of his interest in, such patent; which disclaimer 
  shall be in writing, attested by one or more witnesses, and recorded in the 
  patent office, on payment by the person disclaiming, in manner as, other 
  patent duties are required by law to be paid, of the sum of ten dollars. And 
  such disclaimer shall thereafter be taken and considered as part of the 
  originals specification, to the extent of the interest which shall be 
  possessed in the patent or right secured thereby, by the disclaimant, and by 
  those claiming by or under him subsequent to the record thereof. But no such 
  disclaimer shall affect any action pending at the time of its being filed, 
  except so far as may relate to the question of unreasonable neglect or delay 
  in filing the same. 
      5. Assignment of patents. 
      44. By virtue of the act of July 4, 1836, sect. 11, every patent shall 
  be assignable in law, either as to the whole interest, or, any undivided 
  part thereof, by any instrument in writing; which assignment, and also every 
  grant and conveyance of the exclusive right under any patent, to make and 
  use, and to grant to others to make and use, the thing patented within and 
  throughout any, specified part or portion of the United States, shall be 
  recorded in the patent office within three months from the execution 
  thereof. This act required the payment of a fee of three dollars to be paid 
  by the assignee, but this provision has been repealed by the act of March 3, 
  1839, s. 8, and such assignments, grants, and conveyances, shall, in future, 
  be recorded without any charge whatever. But, by the act of May 27, 1848, 
  Minot's. Stat. at Large, U. S. 231, it is enacted, That hereafter the 
  commissioner of patents shall require a fee of one dollar for recording any 
  assignment, grant or conveyance, of the, whole or any part of the interest 
  in letters-patent, or power of attorney, or license to make or use the 
  things patented, when such instrument shall not exceed three hundred words; 
  the sum of two dollars when it shall exceed three hundred, and shall not 
  exceed one thousand words and the sum of three dollars when it shall exceed 
  one thousand words; which fees shall in all cases be paid in advance. 
      6. The extension of the patent. 
      45. The act of July. 4, 1836, sect. 18; directs, That whenever any 
  patentee of an invention or discovery shall desire an extension of his 
  patent beyond the term of its limitation, be may make application therefor, 
  in writing, to the commissioner of the patent office, setting forth the 
  grounds thereof, and the commissioner shall, on the applicant's paying the 
  sum of forty dollars to the treasury, as in the case of an original 
  application, for a patent, cause to be published, in one or more of the 
  principal newspapers in the city of Washington, and in such other paper or 
  papers as he may deem proper, published in the section of country most 
  interested adversely to the extension of the patent, a notice of such 
  application and of the time and place when and where the same will be 
  considered, that any, person may appear and show cause why the extension 
  should not be granted. And the secretary of state, the commissioner of the 
  patent office, and the solicitor of, the treasury, shall constitute a board 
  to hear and decide upon the evidence produced before them both for and 
  against the extension, and shall sit for that purpose at the time and place 
  designated in the published notice thereof. The patentee shall furnish to 
  said board a statement, in writing, under oath, of the ascertained value of, 
  the invention, and of his receipts and expenditures, sufficiently in detail 
  to exhibit a true and faithful account of loss and profit in any manner 
  accruing to him from and by reason of said invention. And if, upon a hearing 
  of the matter, it shall appear to the full and entire satisfaction of said 
  board, having due regard to the public interest therein, that it is just and 
  proper that. the term of the patent should be extended by reason of the 
  patentee, without neglect or fault on his part, having failed to obtain, 
  from the use and sale of his invention, a reasonable remuneration for the 
  time, ingenuity and expense bestowed upon the same, and the introduction 
  thereof into use, it shall be the duty of the commissioner to renew and 
  extend the patent, by making a thereon of such extension, for the term of 
  seven years from and after the expiration of the first term; which 
  certificate, with a certificate of said board of their judgment and opinion 
  as aforesaid, shall be entered on record in the patent office; and thereupon 
  the said patent shall have the same effect in law as though it had been 
  originally granted for the term of twenty-one years. And the benefit of 
  such, renewal shall extend to assignees and grantees of the right to use the 
  thing patented, to the extent of their respective interest therein: 
  Provided, however, That no extension of a patent shall be granted after the 
  expiration of the term for which it was originally issued. 
      7. Requisites to secure the patent. 
      46. The act of August 29, 1842, section 6, requires, That all patentees 
  and and assignees of patents hereafter granted, are hereby required to 
  stamp, engrave, or cause to be stamped or engraved, on each article vended, 
  or offered for sale, the date of the patent; and if any person or persons, 
  patentees, or assignees, shall neglect to do so, he, she, or they, shall be 
  liable to the same penalty, to be recovered and disposed of in the manner 
  specified in the foregoing fifth section of this act. See 49. 
      Sec. 7. Duty or tax on patents. 
      47. The tax or duty on patents is not the same in all cases, foreigners 
  being required to pay a greater sum than citizens, and the subjects of the 
  king of Great Britain a greater sum than other foreigners. The ninth section 
  of the act of July 4, 1836, requires, That before any application for a 
  patent can be considered by the commissioner as aforesaid, the applicant 
  shall pay into the treasury of the United States, or into the patent office, 
  or into any of the deposit banks to the credit of the treasury, if he be a 
  citizen of the United States, or an alien, and shall have been resident in 
  the United States for one year next preceding, and shall have made oath of 
  his intention to become a citizen thereof, the sum of thirty dollars; if a 
  subject of the king of Great Britain, the sum of five hundred dollars; and 
  all other persons the sum of three hundred dollars, for which payment 
  duplicate receipts shall be taken, one of which to be filed in the office of 
  the treasurer. And the moneys received into the treasury under this act, 
  shall constitute a fund for the payment of the salaries of the officers and 
  clerks herein provided for, and all other expenses of the patent office, and 
  to be called the patent fund. 
      48. When an applicant withdraws his application before the issuing of 
  the patent, he is entitled to receive back twenty dollars of the sum he may 
  have paid into the treasury. Act of July 4, 1836, sect. 7. And the act of 
  March 3, 1837, section 12, enacts, That whenever the application of any 
  foreigner for a patent shall be rejected and withdrawn for want of novelty 
  in the invention, pursuant to the seventh, section of the act to which this 
  is additional, the  certificate thereof of the commissioner shall be a 
  sufficient warrant to the treasurer to pay back to such applicant two-thirds 
  of the duty he shall have paid into the treasury on account of such 
  application. When money has been paid by mistake, as for foes accruing at 
  the patent office, it must, by the direction of the act of August 29, 1842, 
  section 1, be refunded. 
      Sec. 8. Penalty for use of patentee's marks. 
      49. The act of August 29, 1842, s. 5, declares, That if any person or 
  persons shall paint or print, or mould, cast, carve, or engrave, or stamp, 
  upon any thing made, used, or sold, by him, for the sole making or selling 
  which he hath not or shall not have obtained letters-patent, the name or any 
  imitation of the namer of any other person who hath or shall have obtained 
  letters-patent for the sole making and vending of such thing, without 
  consent of such patentee or his assigns or legal representatives; or if any 
  person, upon any such thing not having been purchased from the patentee, or 
  some person who purchased it from or under such patentee, or not having the 
  license or consent of such patentee, or his assigns or legal 
  representatives, shall write paint, print, mould, carve, engrave, stamp, or 
  otherwise make or affix the word "patent," or the words "letters-patent," or 
  the word "patentee," or any word or words of like kind, meaning, or import, 
  with the view or intent of imitating or counterfeiting the stamp, mark, or 
  other device of the patentee, or shall affix the same or any word, stamp, or 
  device, of like import, on any unpatented article, for the purpose of 
  deceiving the public, he, she, or they, so offending, shall be liable for 
  such offence, to a penalty of not less than one hundred dollars, with costs, 
  to be recovered by action in any of the circuit courts of the United States, 
  or in any of the district courts of the United States, having the powers and 
  jurisdiction of a circuit court; one-half of which penalty, as recovered, 
  shall be paid to the patent fund, and the other half to any person or 
  persons who shall sue for the same. 
      Sec. 9. Courts having jurisdiction in patent cases. 
      50. It is enacted by the 17th section of the act of July 4, 1836, That 
  all actions, suits, controversies, and cases arising under any law of the 
  United States, granting or confirming to inventors the exclusive right to 
  their inventions or. discoveries, shall be originally cognizable, as well in 
  equity as at law, by the circuit courts of the United States, or any 
  district court having the powers and jurisdiction of a circuit court which 
  courts shall have power, upon bill in equity filed by any party aggrieved, 
  in any such case, to grant injunctions, according to the course and 
  principles of courts of equity, to prevent the violation of the rights of 
  any inventor as secured to him by any law of the United States on such terms 
  and conditions as said courts may deem reasonable: Provided, however, That 
  from all judgments and decrees, from. any, such court rendered in the 
  premises, a writ of error or appeal, as the case may require, shall lie to 
  the supreme court of the United States, in the same manner and under the 
  same circumstances as is now Provided by law in other judgments and decree, 
  of circuit courts, and in all other case's in which the court shall deem, it 
  reasonable to allow the same. 
      Sec. 10. Actions for violation of patent rights. 
      51. The act of July 4, 1836, section 14, provides, That whenever in any 
  action for damages for making, using, or selling the thing whereof the 
  exclusive right is secured by any patent heretofore granted, or by any 
  patent which may hereafter be granted, a verdict shall be rendered for the 
  plaintiff in such action, it shall be in the power of the court to render 
  judgment for any sum above the amount found by such verdict as the actual 
  damages sustained by the plaintiff, not exceeding three times the amount 
  thereof, according to the circumstances of the case, with costs; and such 
  damages may be recovered by action on the case, in any court of competent 
  jurisdiction, to be brought in the name or names of the person or persons 
  interested, whether as patentee, assignees, or as grantees of the exclusive 
  right within and throughout a specified part of the United States. 
      52.-Sect. 15. That the defendant in any such action shall be permitted 
  to plead the general issue, and to give this act, and any special matter in 
  evidence, of which notice in writing may have been given to the plaintiff or 
  his attorney, thirty days before trial, tending to prove that the 
  description and specification filed by plaintiff does not contain the whole 
  truth relative to his invention or discovery, or that it contains more than 
  is necessary to produce the described effect; which concealment or addition 
  shall fully appear to have, been made for the purpose of deceiving the 
  public, or that the patentee was not, the original and first inventor or 
  discoverer of the thing patented, or of a substantial and material art 
  thereof claimed as new, or that it had teen described in some public work 
  anterior to the supposed discovery thereof by the patentee, or had been in 
  public use, or on sale with the consent and allowance of the patentee before 
  his application for a patent, or that, he had surreptitiously or unjustly 
  obtained the patent for that which was in fact invented or discovered by 
  another, who was using reasonable diligence in adapting and perfecting the 
  same; or, that the patentee if an alien at the time the patent was granted, 
  had failed and neglected for the space of eighteen months from the date of 
  the patent, to put and continue on sale to the public, on reasonable terms, 
  the invention or discovery for which the patent issued; in either of which 
  cases judgment shall be rendered for the defendant, with costs. And whenever 
  the defendant relies in his defence on the fact of a previous invention, 
  knowledge, or use of the thing patented, be shall state, in his notice of 
  special matter, the names and places of residence of those whom he intends 
  to prove to have possessed a prior knowledge of the thing and where the same 
  had been used: Provided, however, that whenever it shall satisfactorily 
  appear that the patentee, at the time of making his application for the 
  patent, believed himself to be the first inventor or discoverer of the thing 
  patented the same shall not be held to be void on account of the invention 
  or discovery or any part thereof having been before known or used in any 
  foreign country, it not appearing that the same or any substantial part 
  thereof, had before been patented or described in any printed publication. 
  And provided, also, that whenever the plaintiff shall fail to sustain his 
  action on the ground that in his specification of claim is embraced more 
  than that of which he was the first inventor, if it shall appear that the 
  defendant had used or violated any part of the invention justly and truly 
  specified and claimed as new, it shall be in the power of the court to 
  adjudge and award as to costs as may appear to be just and equitable. 
      53. This last section has been modified by the act of March 3, 1837, 
  which enacts as follows: Section 9, That anything in the fifteenth section 
  of the act to which this is additional to the contrary notwithstanding That, 
  whenever by mistake, accident, or inadvertence, and without any willful 
  default or intent to defraud or mislead the public, any patentee shall have 
  in his specification claimed to be the original and first inventor or 
  discoverer of any material or substantial part of the thing patented, of 
  which he was not the first and original inventor, and shall have no legal or 
  just right to claim the same in every such, case the patent shall be deemed 
  good and valid for so much of the invention or discovery as shall be truly 
  and bona fide his own: Provided, it shall be a material and substantial part 
  of the thing patented, and be definitely distinguishable from the other 
  parts so claimed without right as aforesaid. And every such patentee, his 
  executors, administrators and assigns, whether of the whole or of a 
  sectional interest therein, shall be entitled to maintain a suit at law or 
  in equity on such patent for any infringement of such part of the invention 
  or, discovery as shall be bona fide his own as aforesaid, notwithstanding 
  the specification may embrace more than he shall have any legal right to 
  claim. But, in every such case in which a judgment or verdict shall be 
  rendered for the plaintiff he shall not be entitled to recover costs against 
  the defendant, unless he shall have entered at the patent office, prior to 
  the commencement of the suit, a disclaimer of all that part of the thing 
  patented which were so claimed without right: Provided, however, That no 
  person bringing any such suit shall be entitled to the benefits of the 
  provisions contained in this section, who shall have unreasonably neglected 
  or delayed to enter at the patent office a disclaimer as aforesaid. See Bac.
