Patent

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.

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 req
