PATENTS , properly documents conferring some
See also:privilege, right, &c.,
See also:short for " letters patent " (q.v.) . Patents for inventions,
See also:instruments which formerly
See also:bore the
See also:great seal of the
See also:Kingdom, are now issued at the Patent
See also:Office in
See also:London under the seal of that office . By their means inventors obtain a
See also:monopoly in their inventions for fourteen years, a
See also:term which, if insufficient to remunerate the inventor, can be extended . This monopoly is founded on exactly the same principle as the
See also:copyright enjoyed by authors and artists . There are persons who argue that no such privilege should be permitted; there are others who think that the most trifling exertions of the inventive faculties should be protected . The right course clearly lies between these extremes . To
See also:grant a very long term of exclusive possession might be detrimental to the public, since it would tend to stop the progress of improvement . A limited
See also:property must therefore be allowed—large enough to give the inventor an opportunity of
See also:reaping a
See also:reward, but not barring the way for an unreasonable
See also:period . And, when this compromise has been decided on, it will be seen how difficult it may be to determine beforehand what is the real merit of an invention, and apportion the
See also:time to that merit . Hence it has been found necessary to allot one fixed period for all kinds of inventions falling within the purview of the patent
See also:laws . United Kingdom.—Formerly the reigning
See also:prince considered himself entitled, as
See also:part of his
See also:prerogative, to grant privileges of the nature of monopolies to any one who had gained his favour . These grants became so numerous that they were oppressive and unjust to various classes of the
See also:commonwealth; and hence, in the reign of
See also:James I., a
See also:statute was wrung from that
See also:king which declared all monopolies that were grievous and inconvenient to the subjects of the
See also:realm to be void .
(See LETTERS PATENT; MONOPOLY.) There was, however, a
See also:special exception from this enactment of all letters patent and grants of privilege of the "
See also:sole working or making of any manner of new manufacture within the realm to the true and first inventor of such manufacture, which others at the time of making such letters patent and grants should not use, so they be not contrary to
See also:law, nor mischievous to the state by raising of the prices of commodities at home or hurt of
See also:trade or generally inconvenient." Upon these words hangs the whole law of letters patent for inventions . Many statutes were afterwards passed, but these were all repealed by the Patent
See also:Act of 1883 (46 & 47 Vict . C . 57), which, besides introducing a new procedure, modified the law in several particulars . Subsequently acts amending the law were passed in 1885, 1886, 1888, 1901, 1902 and 1907 . These acts, with the exception of certain sections of the act of 1883, were repealed by a consolidating act, the Patents and Designs Act 1907, which also introduced new provisions into
See also:English patent law . Where the law is not expressly laid down by act of parliament, it has to be gathered from the numerous decisions of the courts, for patent law is to no inconsiderable extent "
See also:judge-made law." The inventions for which patents are obtained are chiefly either vendible articles formed by chemical or
See also:mechanical operations, such as
See also:cloth, alloys, vulcanized india-
See also:rubber, &c., or machinery and apparatus, or processes . It may be remarked here that a scientific principle cannot
See also:form the subject of a valid patent unless its application to a
See also:practical and useful end and
See also:object is shown . An abstract notion, a philosophical idea, may be extremely valuable in the realm of science, but before it is allowed to form a sound basis for a patent the
See also:world must be shown how to apply it so as to gain therefrom some immediate material
See also:advantage . With regard to processes, the language of the statute of James has been strained to bring them within the words " any manner of new manufacture," and
See also:judges on the
See also:bench have admitted that the exposition of the act has gone much beyond the
See also:letter . However, it is undoubted law that a
See also:process is patentable; and patents are accordingly obtained for processes every
See also:day . The
See also:principal classes of patentable inventions seem to be these: (1) new contrivances applied to new ends, (2) new contrivances applied to old ends, (3) new combinations of old parts, whether
See also:relating to material
See also:objects or processes, (4) new methods of applying a well-known object .
With regard to a patent for the new application of a well-known object it may be remarked that there must be some display of ingenuity, some amount of invention, in making the application, otherwise the patent will be invalid on the ground that the subject-
See also:matter is destitute of novelty . For example, a fishplate, used before the introduction of
See also:railways to connect 904 wooden beams could not be patented to connect the rails of a railway (Harwood v . Great
See also:Northern Railway Co., r86o-1865, Ir H . L . C . 654); nor can a
See also:spring long used in the
See also:rear of a
See also:carriage be patented for use in the front (
See also:Morgan v . Windover, 1890, 7 R . P . C . 131) . But a small amount of invention will suffice, so long as the improvement is manifest, either as saving time or labour (Rickmann v .
See also:Thierry, 1896, 14 R.P, C .
105: Patent Exploitation, Ltd. v .Siemens& Co., 1904, 21 R.P.C . 549) . Whatever be the nature of the invention, it must possess the incidents of utility and novelty, else any patent obtained in respect of it will be invalid . The degree of utility need not, however, be great . As to novelty, this is the
See also:rock upon which most patents split; for, if it can be shown that other persons have used or published the invention before the date of the patent, it will fall to the ground, although the patentee was an
See also:independent inventor deriving his ideas from no one else . The difficulty of steering clear of this rock will be apparent at once . Suppose A in London patents an invention the result of his own ingenuity and patient study,. and it afterwards appears that B, in some distant part of the kingdom, had been previously openly using the same thing in his workshop, A's patent is
See also:good for nothing . Thus, where the patent sued on was a
See also:lock, it was proved that a similar lock had been in use on a
See also:gate adjoining a public road for sixteen years
See also:prior to the patent, which was accordingly invalidated (
See also:Carpenter v .
See also:Smith, 1842, I
See also:Web . P.C . 540) .
It is therefore a very frequent subject of inquiry, whether an invention has been previously used to such an extent as to have been publicly used in the sense attached by the courts to this phrase . But whereas " user " in public is sufficient prior publication to invalidate a subsequent patent for the invention so used, publication in books, &c., will not be a
See also:bar to novelty unless its effect is to make the invention actually a part of public knowledge; and in dealing with alleged anticipations by patents that have never come into general use the courts will not invalidate a subsequent patent unless a
See also:person of ordinary knowledge of the subject, on having the alleged anticipation brought under his
See also:notice, would at once perceive, understand, and be able practically to apply the invention without making experiments or seeking for further information . The inventor himself is not allowed to use his invention, either in public or secretly, with a view to profit, before the date of the patent . Thus, if he manufactures an article by some new process, keeping the process an entire secret, but selling the produce, he cannot afterwards obtain a patent in respect of it . If he were allowed to do this he might in many cases easily obtain a monopoly in his invention for a much longer period than that allowed by law (Morgan v . Seaward, 1837, r Web . P.C . 192) . The
See also:rule that an inventor's use of the invention invalidates a subsequent patent does not, however, apply to cases where the use was only by way of experiment with a view to improve or test the invention (
See also:Elias v . Grovesend Tinplate Co., 1890, 7 P.O.R . 466) . And it has been repeatedly decided that the previous experiments of other persons, if in-
See also:complete or abandoned before the realization of the
See also:discovery, will not have the effect of vitiating a patent .
Even the prior discovery of an invention will not prevent another independent discoverer from obtaining a valid patent if the earlier inventor kept the secret to himself, the law holding that he is the " true and first inventor " who first obtains a patent . The Patents Act 1883 provided that the
See also:exhibition of an invention at an
See also:industrial or
See also:international exhibition certified as such by the
See also:Board of Trade, or the publication of any description of the invention during the period of the holding of the exhibition, or its use for the purpose of the exhibition in the place where it is held, or during the period of the exhibition by any person else-where, without the privity or consent of the inventor, should not
See also:prejudice the right of the inventor or of his legal
See also:personal representative to apply for and obtain a patent, or the validity of any patent granted on the application, provided that two conditions are complied with, viz . (a) the exhibitor must, before exhibiting the invention, give the
See also:Comptroller-General a pre-scribed notice of his intention to do so; and (b) the application for the patent must be made before or within six months from thedate of the opening of the exhibition . The Patents Act 1886, enabled the
See also:Sovereign, by
See also:order in council, to extend the
See also:pro-vision above mentioned to industrial and international exhibitions held out of the United Kingdom . The act of 1907 re-enacted these provisions (§§ 45, 59) . When an invention is the joint production of more persons than one, they must all apply for and obtain a joint patent, for a patent is rendered invalid on showing that a material part of the invention was due to some one not named therein . The mere
See also:suggestion of a workman employed by an inventor to carry out his ideas will not, however, require that he should be joined, provided that the former adds nothing substantial to the invention, but merely
See also:works out in detail the principle discovered by his employer . Procedure.—The attributes of novelty and utility being possessed in due degree by an invention, it remains to put in motion the machinery for its
See also:protection . The Patents Act 1907, re-enacting former provisions, requires an application to be made in a prescribed form (the forms and stamps are on sale at all postal
See also:money order offices in the United Kingdom), and
See also:left at or sent by
See also:post to the patent office in the prescribed manner . The application must contain a declaration that the applicant is the true and first inventor, and it must be accompanied by either a provisional or complete
See also:specification . A provisional specification describes the nature of an invention, and a complete specification particularly describes and ascertains the nature of the invention and the manner in which it is to be performed . Since the introduction of the patent specification, it has been necessary that an invention pro- - tected by patent should be accurately described by the inventor .
Formerly, when the
See also:condition on which letters patent issued was that the patentee should
See also:file a specification completely describing the nature of his invention• within a certain time after the grant, the
See also:function of giving the necessary preliminary information on the subject was to some extent discharged by the title; at any
See also:rate, the validity of the grant was liable to be objected to on the ground of the title being too general . Under the
See also:present law the task of preliminary disclosure falls to the provisional specification, introduced by the Patent Law Amendment Act 1852, and continued by the Patents Acts of 1883 and 1907, although a patentee may, under the latter statutes, dispense with a provisional specification if he thinks proper to file a complete one in the first instance . Where however, these two specifications are filed, it becomes of vital moment to an inventor that the true relation between them should be maintained as defined above . The object of the provisional specification is to secure immediate protection, and to enable a patentee to
See also:work at and improve his invention without the
See also:risk of his patent being invalidated by premature publication . He is therefore entitled to embody in his complete specification any improved method of working his invention which he may discover in the
See also:interval; and he is indeed bound to do so, since, as we have said, the price that a man who desires a patent has to pay to the public for the privilege is that he should make a full disclosure of his invention in his complete specification . But there is a limit to what the patentee may do in this respect . He must not describe in his complete specification an invention different from that declared in the provisional . If he falls into this error there is said to be a " variance " or " disconformity " between the two specifications . The Patents Act 1883, § 9, made it the
See also:duty of the examiners of the Patent Office to consider the question of disconformity between specifications on applications for patents, but the only power the comptroller had, on discovery of disconformity, was to refuse to accept the specification until the disconforming parts had been eliminated . By the act of 1907, § 6, tie may now refuse to accept the complete specification until it has been amended to his satisfaction, or (with the consent of the applicant)
See also:cancel the provisional specification and treat the application as having been made on the date at which the complete specification was left . Moreover, if the complete specification includes an invention not included in the provisional specification, the application may proceed as a whole, or may be divided, and the claim for the additional invention included in the complete specification be regarded as an application for that invention made on the date at which the complete specification was left . An act of 1902 (which, with the exception of a portion dealing with compulsory licences, came into operation on the 1st of
See also:January 1905) provided for an examination or
See also:search as to novelty, such investigation dealing with
See also:British complete specifications published and dated within fifty years prior to the date of the application .
This search was re-enacted by the act of 1907 (§ 7) and power given to the comp-troller to refuse the grant of a patent in cases in which the invention had been wholly and specifically claimed in specifications to which his search had extended . The term for which a patent is originally granted is fourteen years, but a patentee may, afteradvertisement according to the rules of the Supreme
See also:Court, petition for a further term . The court, in considering its decision, takes regard of the nature and merit of the invention in relation to the public, of the profits made by the patentee as such, and of all the circumstances of the case . If it appears to the court that the patentee has been inadequately remunerated by his patent, it may extend the term of the patent to a further term not exceeding seven or, in exceptional cases, fourteen years, or may order the grant of a new patent for a certain term, with any restrictions or provisions it may think
See also:fit (Act of 1907, § 18) . Patent privileges, like most other rights, can be made the subject of sale . Partial interests can also be carved out of them by means of licences, instruments which empower other persons to exercise the invention, either universally and for the full time of the patent (when they are tantamount to an
See also:assignment of the patentee's entire rights), or for a limited time, or within a limited
See also:district . By an exclusive licence is meant one that restrains the patentee from granting other licences to any one else . By means of a licence a patentee may derive benefit from his patent without entering into trade and without
See also:running the risks of a
See also:partnership . One of the regulations of the act of 1883 was that a patentee could be compelled by the Board of Trade to grant licences to persons who were able to show that the patent was not being worked in the United Kingdom, or that the reasonable requirements of the public with respect to the invention could not be supplied, or that any person was prevented from working or using to the best ad-vantage an invention of which he was possessed . This regulation, however, remained practically a dead letter, for only three applications were made between the years 1883 and 1897, and these never proceeded to a
See also:hearing . After 1897 a few petitions were heard, but even so
See also:late as in 1908 there was only one petition and that was withdrawn by agreement between the parties . By § 3 of the act of 1902, the hearing of petitions for a grant of compulsory licences was transferred to the judicial
See also:committee of the privy council, but the act of 1907 substituted the High Court as the tribunal in the place of the judicial committee .
It also laid down that the reasonable requirements of the public should not be deemed to be satisfied: (a) if byreason of the default of the patentee to manufacture to an adequate extent and supply on reasonable terms, the patented article or any parts thereof necessary for its efficient working or to carry on the patented process to an adequate extent or to grant licences on reasonable terms, any existing trade or
See also:industry or the
See also:establishment of any new trade or industry in the United Kingdom is unfairly prejudiced, or the demand for the patented article is not reasonably met; or (b) if any trade or industry in the United Kingdom is unfairly prejudiced by the conditions attached by the patentee before or after the passing of the act to the
See also:purchase, hire or use of the patented article or to the using or working of the patented process . Clause b is an endeavour to remedy an abuse by which patentees bound down purchasers and licences by all kinds of conditions . Section 38 of the act of 1907 contains also a further remedy, making it unlawful in any contract in relation to the sale or lease of, or licence to use or work, any patented article or process to insert conditions prohibiting or restricting the use of the patent or process from using articles supplied by a third person or requiring him to use other articles not protected by the patent . Such conditions are declared " null and void as being in restraint of trade and contrary to public policy." Another new and very important
See also:provision of the act of 1907 is that dealing with the revocation of patents worked outside the United Kingdom . It may be stated here that in the
See also:year 1908 out of a
See also:total number of 16,284 patentees, 2819 were
See also:resident in the United States, 2516 in Germany, 822 in France, 334 in
See also:Austria-Hungary, zoo in
See also:Switzerland, 166 in the Australian Commonwealth, 159 in Belgium, 155 in
See also:Canada, 139 in Sweden and 134 in Italy . It had been a
See also:common practice to take out licences in the United Kingdom (especially in the dyeing industry) in order to close the British market to all except the patentees and their licensees, the patented articles or processes being worked entirely abroad . Section 27 of the act of 1907 enacted that at any time not less than four years after the date of a patent and not less than one year after the passing of the act, any person might apply to the comptroller for the revocation of a patent on the ground that the patented article or process is manufactured or carried on exclusively or mainly outside the United Kingdom . The comp-troller is given power to make an order revoking the patent forth-with or after a reasonable interval, unless the patentee can show satisfactory reasons . The insertion of this provision resulted in the establishment of many factories in the United Kingdom . Legal Remedies.—A patentee's remedy for an infringement of his rights is by
See also:civil suit, there being no criminal proceedings in such a case . In prosecuting such suit he subjects those rights to a searching examination, for the alleged infringer is at liberty to show that the invention is not new, that the patentee is not the true and first inventor, &c., as well as to prove that the alleged infringement is not really an infringement . But it may here be remarked that a patentee is not bound down (unless he chooses so to be) to the precise mode of carrying the invention into effect described in the specification .
If the principle is new, it is not to be expected that he can describe every mode of working it; he will sufficiently secure the principle by giving some illustrations of it; and no person will be permitted to adopt some mode of carrying905 the same principle into effect on the ground that such mode has not been described by the patentee . On the other
See also:hand, when the principle is not new, a patentee can only secure the particular method which he has invented, and other persons may safely use other methods of effecting the same object . Instances of this occur every day; and it is well known that scores of patents have been taken out for
See also:screw-propellers, steam-hammers,
See also:water-meters, &c., each of which is limited to the particular construction described, and cannot be extended further . Again, where the invention patented consists of a combination of parts, some old and some new, the whole constituting a new machine or a new process, it is not open to the world to copy the new part and reject the
See also:rest . A man is not permitted to allege that the patent is for a combination, and that, the identical combination not having been used, there has been no infringement . If he has borrowed the substance of the invention, it will be held that he has infringed the patent . At common law a person who, alleging that he has a patent, threatens his rivals in trade, is liable to an
See also:action for damages, but the
See also:plaintiff cannot succeed without showing that the threats were made maliciously . The Patents Act • 1883 provided another remedy—what is known as " the threats action." This has been incorporated in the act of 1907, § 36 . The statute makes the good faith of the patentee threatening legal proceedings no answer to an action brought against him by any person aggrieved by his threats if the acts complained of are not in fact an infringement of the patent, and if the patentee fails with due
See also:diligence to commence and prosecute an action for infringement . Extent and Construction.—The patent when sealed is to have effect in the United Kingdom and the Isle of Man . The act of 1907, unlike the Patent Law Amendment Act of 1852, does not extend the monopoly to the Channel Islands . The patent business of the United Kingdom is transacted at the Patent Office in London under the superintendence of the comp-troller, an officer appointed by the Board of Trade, under whose direction Ile performs his duties .
At this office is kept a
See also:register of all patents issued, of assignments of patents, licences granted under them, &c . An illustrated journal of patent inventions is published at the same office, where printed copies of all specifications can also be obtained . The fees payable to
See also:government on patents were considerably reduced by an order of the Board of Trade which came into operation on the 1st of
See also:October 1892, and may now be paid by convenient
See also:annual instalments . The following are the present fees: before the expiration of the 4th year from the date of the patent, £5 instead of £10; of the 5th year, £6 instead of £10; of the 6th year, £7 instead of £10; of the 7th year, £8 instead of £10; of the 8th year, £9 instead of £15; of the loth year, £11 instead of £2o; of the 11th year, £12 instead of £20: of the 12th year, £13 instead of £20; and of the 13th year, £14 instead of £20 . The preliminary fees amounting to £4 were left untouched by the order but under the Patent Rates of 1905 an additional
See also:fee of £1 is payable on the sealing of the patent . The entire cost of a patent is now reduced from £154 to £100 . A new Patent Office was constructed on the site of the old buildings, the frontage extending from Southampton Buildings into
See also:Inn . The number of applications for patents, which sprang from 5993 in 1883 to 17,110 in 1884, culminated in a total of 30,952 for the year 1892, since which date a steady decline set in down to 1900, when the number was 23,924 . But the numbers went up again, reaching 30,030 in 1906, but only 28,598 in 1908 . The number of patents sealed on application for a given year shows less variation, the minimum being 8775 for 1885 against 16,060 in 1907 . The proportion of
See also:seals to applications varies from about 46 to 50% . The receipts from patent fees in 1908 were £262,890, against a total
See also:expenditure of £179,531 .
Theofficial publications of the Patent Office deserve some notice, as, in the
See also:absence of official investigation into novelty, the onus of search rests with the applicant or his
See also:agent . The procedure has been greatly simplified by the publication, on a
See also:system and at a low rate (Is. per
See also:volume), of illustrated abridgments of specifications . From 1877 practically to date the searcher obtains a
See also:digest of all specifications falling within a given class . To these classes there is a reference
See also:index, known as the " abridgment class and index
See also:key," which at once directs the searcher to his proper class and index heading . Patent Agents.—Patents are frequently obtained through the intervention of persons termed patent agents, who devote them-selves to this branch of business . Their position is now regulated by statute . By the Patents Act 1888, it was provided that no person should, after
See also:July 1, 1889, be entitled to describe himself (and whoever does so knowingly incurs liability to a maximum
See also:penalty of £20) as a patent agent whether by advertisement, description of his place of business or otherwise, without being registered as such in pursuance of the act . But the act preserves the right to
See also:registration of every person who, to the satisfaction of the Board of Trade, shows that he had been bona fide practising as a patent agent before it passed . The Board of Trade is em-powered by this statute to make from time to time general rules for the purpose of carrying out its provisions, and by rules issued in 1889, and reissued in 1891, the Board of Trade delegated to the Institute of Patent Agents (which obtained a royal
See also:charter in 1891) the care of the register of patent agents and the duty of holding the necessary
See also:examinations for entrance into the profession . British Dominions.—The following notes on colonial law give the salient facts . Prior to 1852 British letters patent extended to all the colonies, but the act of 1852 restricted the rights granted to the United Kingdom, Channel Islands and Isle of Man .
See also:Australia.—The Commonwealth Acts are No .
21 of 1903, and No . 19 of 1906 . They are founded on the English act of 1883 and amending acts . They provide for adepartment of patents
See also:con-trolled by a
See also:commissioner " under the
See also:minister" (§ 10 of 1903) . Any person, whether a British subject or not, may apply for a patent (§ 32 of 1903) . The term of a patent is 14 years (§ 64 of 1903) . The Commonwealth or a state may acquire patents compulsorily (§§ 93, 94 of 1903) . The act creates a new class of " patent attorneys " (§ lot, 1903) . There is an examination as to novelty (§ 41 of 1903) . The renewal fees amount to a sum of £5 before the end of the 4th year, and £5 before the end of the 7th year from the date of the patent . Bahama Islands.—The law is regulated by the following acts of the colony: 52 Vict. c . 23; 53 Vict. c .
2; 54 Vict. c . 12.; and 63 Vict. c . 3 . Duration of patent 7 years, with power in
See also:governor to renew for another 7 years, and thereafter for a third period of 7 years . The fees are Do on filing specification, Do for second renewal and £20 for third . Apparently there is no preliminary examination as to novelty . Barbadoes.—Acts of 1903 (No . 31) and of 1908 (No. to) . Duration of patent 14 years . The governor in council has power to grant compulsory licences . Fees are £2, Ios. on filing specification, £50 before the end of the 4th year and £too before the end of the 7th year . No preliminary examination as to novelty .
Bermuda.—Act of 1902 (No . 51), on the lines of that of
See also:Trinidad . British
See also:Guiana.—The law is regulated by ordinance No . 31 of 1902 and is practically the same as the English act of 1883 . The fees are $15 on filing specification and $
See also:loo before the end of 7 years . British
See also:Honduras.—The law of the loth of
See also:September 1862 has been re-enacted with slight modifications (see supplement to Patent Laws of the World, No . 4, 1900) . There is no examination as to novelty . British India.—The law is now governed by Act 5 of 1888, which applies to the whole of British India . Duration of patent is 14 years . A preliminary examination into novelty might apparently be ordered . The following taxes are payable: annual sums of Rs .
50 from the 4th to the 8th year, and of Rs. loo from the 8th to the 13th year of the term . British New
See also:Queensland Patents Acts, No 13 of 1884 and No . 5 of 1886, have been adopted . See British New Guinea ordinance No . 6 of 1889,

See also:Borneo.—Straits Settlements law (No . 12 of 1871), adopted by Patents Proclamation 1887 (No . 1 of 1887) . Canada.—Patent legislation belongs exclusively to the Dominion Parliament [B.N.A . Act 1867, § 91 (22)1 . The existing acts are c . 61 of 1886; 55 & 56 Vict .
C . 24; 56 Vict. c . 34; and act of 1903 . The duration of the patent is 18 years . At the time of application the applicant may pay the full fee required for that term (viz . $6o) or the partial fee required for the term of 6 years ($20) or for the term of 12 years ($40) . If a partial fee only is paid, the amount is stated in the patent, and the patent ceases at the end of the term covered by such partialpayment, unless before the expiration of such term the patentee pays the fee required for the further term of 6 or 12 years, viz . $2o in the former case and $4o in the latter . There is a preliminary examination into novelty by examiners, with an
See also:appeal from the decision of the commissioner of patents to the governor in council . The patent is void unless it is worked in Canada within 2 years, or if after the expiration of 12 months, or any authorized extension of either of these periods, the patentee imports the invention into Canada, but conditions may be substituted for condition as to manufacture in Canada, as, for example, a licence to another to manufacture, &c . Cape of Good Hope.—The law is regulated by act No . 17 of 1860, No .
24 of 1902 and No . 28 of 1904 . There is no preliminary examination into novelty, and the act contains no provisions for compulsory working, or as to the importation of patented articles from abroad .
See also:Ceylon.—The law is now regulated by act 15 of 1906 . The duration of the patent is 14 years, with power vested in the governor in council to grant extensions of 7 and 14 years .

See also:Turkish pounds . United States.—The
See also:American law may be considered at greater length . The Federal Constitution empowered Congress " to pro-mote the progress of science and useful arts by securing for limited times to . inventors the exclusive right to their . . . discoveries." The existing American patent law is based on a series of Acts of Congress passed in virtue of this provision in the constitution, and on the judicial
See also:interpretation of these statutes . Between American and English patent law there is, as will appear in the course of this
See also:sketch, a considerable degree of similarity . The fact is not surprising when it is remembered that the Statute of Monopolies (21 Jac . I. c . 3) was, except in limiting the maximum duration of letters patent for inventions at fourteen years, only declaratory of the common law; and therefore formed part of the original common law of
See also:America .
The English and American patent systems further agree in this, that they contain no provision as to compulsory working, and no prohibition of the importation of patented articles . But there are importantdifferences between the two systems, not merely in points of detail, but in matters affecting the theory and practical working of the law . In England the
See also:consideration for the grant of a patent has all along been mainly the benefit which the public derives from the introduction of a new manufacture . In America greater emphasis is placed on the right of an inventor to have his merits rewarded . Again, under the Statute of Monopolies an inventor's exclusive privilege arises only in regard to inventions not known or used at the date of the grant, although it should be observed that under the
See also:modern Patents Acts the date of a patent, once granted, relates back to the date of the application . In the United States, on the other hand, the right is conferred on inventors to an exclusive privilege in such inventions as were not known or used before their discovery by the patentees . The practical bearing of this difference is explained in an admirable note on " The Statute of Monopolies " in Ruling Cases, sub tit." Patent " (xx . 5) : " It shifts the point of view in the important question of novelty . Many good American inventions have been given away in England by the premature publication in America of the inventor's proceedings . He is interviewed, and an article in the New
See also:Sun, or some other paper, in due time finds its way to England . This does no harm in America; on the contrary, it is good evidence of the date of the actual invention . But it is fatal to a subsequent application in England." The definition of patentability in American law is contained in
See also:sect .
4886 of the Revised Statutes of the United States as amended by an act of the 3rd of March 1897 . In the following passage the amendments are indicated by italics: " Any person who has Invented or discovered any new and useful art, machine, manufacture orcomposition of matter, or any new and useful improvement thereof, not known or used by others in this
See also:country before his invention or discovery thereof, and not patented or described in any printed publication in this or any foreign country before his invention or discovery thereof or more than two years prior to his application, and not in public use or on sale for more than two years prior to his application, unless the same is proved to have been abandoned, may, upon payment of the fees required by law and other due proceedings had, obtain a patent therefor." The effect of the two amendments made by the act of 1897 should first be noted: (i.) The old law failed to state at what time the invention should be known or used by others in America so as to bar a patent; whether before the application or before the invention . This
See also:ambiguity is removed by the use of the words " before his invention or discovery thereof." (ii.) Under the old law a foreign patentee could take out a patent in America for the same invention at any time during the
See also:life of the foreign patent, provided it had not been in use in America more than two years prior to his application, unless anticipated by a prior invention or publication . The words " or more than two years prior to his application," merely give the same force to a foreign patent or publication that had previously been given to prior use . An invention to be patentable must, according to American law, be both novel and useful . Utility may be evidence of novelty and
See also:vice versa, and commercial success is relevant evidence of utility . As in England, a
See also:bare principle is not patentable . A process " is included under the words " useful art " in the above definition of patentability, and is good subject matter for a patent when the term is used to represent a practical method of producing a beneficial result or effect . The word " machine " in the definition includes every mechanical
See also:device or combination of devices for producing certain results . Such a device or combination is patentable when it possesses utility and novelty, and produces either a new result or an old result in a better form . Under the law of 1790, which was exclusively American in spirit, the duty of granting letters patent for inventions was discharged by the secretary of state, the secretary of war and the attorney-general, or any two of them . The law from 1793 to 1836 was exclusively English in spirit, and during that period the duty fell to the secretary of state, subject to the attorney-general's approval .
It was in 1837 that the marked divergence between the English and American patent system began . In that year the patent business of the United States had attained to such dimensions that the
See also:powers and duties of the secretary of state in regard to patents were transferred to a sub-department of the state department known as the Patent Office . The American Patent Office consists of a commissioner of patents, one assistant commissioner, and three examiners-in-chief, who are appointed by the President of the United States with the advice and consent of the
See also:Senate; and also of other examiners, and a
See also:staff of
See also:officers, clerks and employes, appointed by the secretary of the interior on the nomination of the commissioner of patents . The commissioner of patents, under the direction of the secretary of the interior, is charged with the superintendence or performance of all duties respecting the grant and issue of patents, and has the

He is authorized to make, from time to time, regulations not inconsistent with law, for the conduct of proceedings in the Patent Office, and pre-pares an annual report which is laid before Congress, and which is framed on the same lines as that of the comptroller-general in England . " He is the final judge, so far as the Patent Office is concerned, of all controverted questions arising in the office, and in granting or withholding patents he is not bound by the decisions of his inferiors " (
See also:Robinson on Patents, i . 84) . The examinersin-chief are required to he persons of competent legal knowledge and ability . Their duties are: On the written petition of inventors to revise and determine upon the validity of the adverse decisions of subordinate examiners, upon applications for patents, and for reissues of patents, and in interference cases, and when .required by the commissioner of patents to hear and report upon claims for extension, and to do such other similar work as he may assign to them . The Patent Office publishes an Official
See also:Gazette corresponding to the English Patent Office Illustrated Journal, and discharges similar functions to those of the English Patent Office in regard to the public dissemination of information as to patented inventions . The number of original applications for patents in the period covered by the report of the commissioner of patents for 1906–1907 was 58,762; the number of patents granted was 36,62o; the receipts amounted to $1,910,618, the expenditure to $1,031,458, leaving a surplus of $279,160 . The first step in the procedure to obtain a patent is the lodging by the inventor at the Patent Office of a written application, together with a specification of particular written description of his invention, and a claim distinctly pointing out and claiming what he alleges to be his invention or discovery .
The specification and claim are signed by the inventor and attested by two witnesses . Drawings, specimens of ingredients, and models may be required to be furnished . On the filing of each original application for a patent, a fee of $15 is payable . The applicant is required to verify his claim to the invention on

See also:diplomatic or commercial agent of the United States, or any
See also:notary public of the foreign country in which the applicant maybe . The commissioner of patents then causes an examination to be made into the novelty of the invention, and if the result is satisfactory the patent issues . On the issuing of each original patent, a fee of $20 is payable . A patent is issued in the name of the United States of America and under the seal of the Patent Office . It consists of a short title or description of the invention or discovery, correctly indicating its nature and design, and a grant to the patentee, his heirs and assigns . Patents, it may be observed in passing, may be granted and issued or re-issued to the assignee of the inventor or discoverer, and every patent or any interest in it is assignable, the assignment being recorded in the Patent Office, for the term of seventeen years, of the exclusive right to make use of and vend the invention or discovery throughout the United States and the territories thereof . The rights of property in patents granted in
See also:Porto Rico, the Philippines and other ceded territory under
See also:Spanish law are to be respected in those territories as if that law were still in force there . A patent is dated as of a day not later than three months from the time at which it was passed, and if the fee is not paid within six months the patent is withheld . In case, however, the issue of a patent has been prevented by a failure to pay the fee within the prescribed period, the application may be renewed within 2 years after the
See also:allowance of the original application .
But the applicant has no right to damages for any use of the invention in the interval, and on the hearing of the renewed application abandonment may be considered as a question of fact . So far we have followed the procedure to obtain a patent where its course is uninterrupted . A
See also:double form of interruption is, however, possible . A claim for a patent may be rejected on the ground of want of novelty in the alleged invention . In this case, the fact of the rejection, together with the reasons for it, is communicated to the applicant by the commissioner; and if he persists in his claim a re-examination is ordered . Or, again, an application may appear to the commissioner to interfere with a pending application,' or with any expired patent . In these circumstances, he gives notice to the applicant, and directs the
See also:primary examiner to proceed to determine the question of priority of invention . This interruption of the course of the proceedings to obtain a patent is called an " interierence." In either of the cases above mentioned an appeal lies, on payment of a fee of $1o, from the primary examiner to the board of examiners-in-chief, and, on payment of a fee of $20, from the examiners-in-chief to the commissioner in person . An applicant for a patent, but not a party to an interference, may appeal from the decision of the commissioner to the supreme court of the District of
See also:Columbia sitting in bane . In interference cases the appeal lies to the District of Columbia court of appeals . There is an ultimate right of appeal, in cases involving the validity of a patent, to the Supreme Court of the United States . Patents are obtainable by bill in
See also:equity, although the commissioner of patents (or, on appeal, the supreme court of the District of Columbia) may have refused them .
Thecircuit courts of the United States have original jurisdiction in all patent suits . Appellate jurisdiction is vested in the circuit court of appeals; and on the certificate of that court, or by certiorari, an appeal may be brought to the Supreme Court of the United States . Section 4887 of the revised statutes provides that: " No person otherwise entitled thereto shall be debarred from receiving a patent for his invention or discovery, nor shall any patent be declared invalid by reason of its having been first patented or caused to be patented by the inventor or his legal representatives or assigns in a foreign country, unless the application for the said foreign patent was filed more than seven months prior to the filing of the application in this country, in which case no patent shall be granted sn this country." The words italicized in the above section were added by an Amending Act of the 3rd of March 1897 . In its original form the section provided that no person should be debarred from receiving a patent because the invention was first patented in a foreign country, whether he was otherwise entitled to the patent or not . The words " other-wise entitled to " merely postulate that no other bar to the issue of the patent shall exist . The words " by the inventor or his legal representatives or assigns " safeguard the inventor to some extent against
See also:fraud by third parties; while the provision requiring the application in the United States to be filed within seven months of the filing of the foreign patent is intended to carry out the pro-visions of the International
See also:Convention . It should be noted that the duration of an American patent for an invention already patented abroad is no longer limited by that of the prior foreign patent, but is granted for 17 years from the date of issue . Patented articles are required to be marked as such, either by the word " patented," together with the day and the year the patent was granted, being affixed to them, or, when from the character of the article this cannot be done, by fixing to it, on the package containing one or more of such articles, a
See also:label containing the like r A citizen of the United States, or an alien who has within the preceding twelve months given notice of his intention to become one, may, by filing in the Patent Office a " caveat," the fee for which is $1o, secure for himself notice of possibly conflicting applications . notice; and in any suit for infringement by a party failing so to mark, no damages shall be recovered by the plaintiff, except on
See also:proof that the
See also:defendant was duly notified of the infringement, and continued after such notice to make, use or vend the article so patented . A penalty of not less than loo dollars is attached to falsely marking or labelling articles as patented . When through inadvertence, accident or
See also:mistake, and without fraudulent or deceptive intention, a patentee has claimed more than he is entitled to, his patent is valid for all that part which is truly and justly his own; provided this is a material or substantial part of the thing patented and the patentee, or his heirs or assigns, on payment of the prescribed fee ($to) disclaim the surplusage . The
See also:disclaimer must be in writing, and attested by one or more witnesses; it is recorded in the Patent Office, and is thereafter considered a part of the original specification .
But no disclaimer affects any action pending at the time of its being filed, except so far as may relate td the question of unreasonable neglect or delay in filing it . In the same circumstance, or where a patent is inoperative or invalid by reason of a defective or insufficient specification, the patentee may surrender his patent, and the commissioner of patents may, on the application of the patentee and on payment of a fee of $30, issue a new patent in accordance with the amended specification .

See also:November 1885).—The term is 3, 6 or 9 years, at the option of the applicant . There is an annual tax of $25 for every year of the privilege .

See also:Venezuela.—A new law was promulgated by a decree of the 19th of March 1900, but revoked in January 1901 and the old law of 1882 substituted . The term is 5, 10 or 15 years . The tax is 8o francs (bolivars) a year if the patent is for an invention or discovery, and 6o francs (bolivars) a year if it relates to an improved process . There is no preliminary examination as to novelty, nor is there any compulsory working . International Patents.—The International Convention for the protection of industrial property was signed at
See also:Paris on the loth of March 1883; the necessary ratifications were exchanged on the 6th of June 1884, and the Convention came into force a
See also:month later . Provision was made by sections 103 and 104 of the Patents Act 1883 for carrying out the Convention in Great Britain by orders in council, applying it from time to time to (a) British possessions whose legislatures had made satisfactory arrangements for the protection of inventions patented in Great Britain; (b) foreign states with which the sovereign had made arrangements for the mutual protection of inventions .
