Weston v. White
Opinion of the Court
This is a motion for a preliminary injunction to restrain the defendants from an infringement of letters patent granted to Thomas A. Weston, on August 6th, 1867, for differential pulley blocks. English letters patent bearing date April 25th, 1859. and published October 22d, 1859, had been issued to Hr. Weston, for the-same invention. It has been decided by this court [Case No. 17,458] that the American patent will expire on October 22d, 1876. The defendants do not deny infringement, and do not substantially deny the patent-ability of the invention, or that Weston was the first and original inventor. The validity of the patent seems now to be generally conceded in this country, although no adjudication has ever been had in our own courts. In the case of Tangye v. Stott [14 Wkly. Rep. 128], which was tried before Sir W. P. Wood, Vice Chancellor, and a special jury, in December. 1865, the priority of Weston’s claim to originality, and the validity of the English patent, were sustained by the verdict. Where no question is made as to infringement or priority, or as to the novelty or patentability of the invention, and where the public generally have acquiesced in the claim of the patentee to a monopoly, an adjudication by a court of law or of equity is not required before a preliminary injunction will be granted.
The objection to the validity of the patent is upon the ground that, prior to the application upon which the patent was issued, and which application was dated October 3d, 1866, the patented article had been in public or common use in this country. The history of the invention, and of the various applications by Weston for a patent, and of the use of the invention in this country, is as follows; Weston, on December 31st, 1859, filed in the .patent office a caveat for this invention, which was renewed, and was in force until December 31st, 1861. On December 6th, 1860. J. J. Doyle filed his application for a patent for substantially the same invention, and a patent was issued to him on January 8th, 1861. The commissioner of patents did not give Weston the notice required by the 12th section of the act of July 4th, 1836 (5 Stat. 121), of the existence of Doyle’s application. The examiner of the patent office, in his decision of June 8th, 1867. upon an interference between Doyle and Weston, says; “Notwithstanding the fact, that Weston had a caveat properly filed and in full force, Doyle files an application and obtains his patent for the pulley which is fully described in said caveat, without the slightest reference being had to the latter. The fact cannot be denied, that Doyle’s patent, under the circumstances, no notice having been taken of Weston’s caveat, was improperly issued, and that an act of great injustice, unintentionally, of course, was perpetrated towards Weston.” On December 14th, 1861, Weston made an application for a patent for the invention described in his caveat, which application was refused on December 18th, 1861, on account of the existence of Doyle’s patent. In July, 1862, Weston, who had been in England since the year 1858. first heard of the rejection of his application. In March, 1863, he took meas
In 1863, Samuel Hall’s Son & Co., a firm in the city of New York, made and Sold differential pulleys, which were exact imitations of the patented invention, although they were stamped as if made under Doyle’s patent. The Doyle pulley was not successful. In 1864, the firm removed to Newark, and engaged in the business upon quite a large scale. James Bird, of New York, also made the same pulleys in 1865. The defendants base their objection to the validity of the patent upon the ground that the manufacture and sale of the Weston pulleys, in 1863, 1864 and 1865, constituted a public or common use of the patented article, prior to the application of Weston for his patent in 1866, and that, therefore, the patent is invalid, under the 6th and 7th sections of the act of March 3d, 1839 (5 Stat. 354).
There is no doubt that the Weston pulleys were in public or common use in this country as early as the year 1803, and, if no application had been made by Weston prior to December, 1866, or if the prior application which he did make had been abandoned, it is true that the patent would be invalid. But, it is found that an application was made in 1861, which was improperly rejected, and which was not withdrawn until October, 1866, when it was withdrawn for the purpose of filing a new application for the same invention which was originally claimed, and that the application of 1860 was intentionally in continuation of the previous application for substantially the same invention, and that no laches or fault is attributable to Weston for this apparent delay after the first rejection of his application, and that he had neither abandoned his application nor his invention. “If an applicant for a patent choose to withdraw his application for a patent, intending, at the time of such withdrawal, to file a new petition, and he accordingly does so, the two petitions are to be considered as parts of the same transaction, and both as constituting one continuous application, within the meaning of- the law.” Godfrey v. Eames, 1 Wall. [68 U. S.] 317. This statement of the law presupposes that the original application is an existing, and not an abandoned, application. Por, it is believed that the supreme court “did not intend to decide that every subsequent application for a patent should be deemed, in judgment of law, to relate back to the first, whatever the interval of time, of the intervening acts of the applicant between them,” although the applicant might have wished or intended that such result should take place, when he filed his new application. Bevin v. East Hampton Bell Co. [Case No. 1,379]. The continuity of the two applications is a question of fact, to be determined, in each case, upon an examination of its own circumstances. In order to ascertain this fact, the trier will find whether the inventor has abandoned his original application, either by his own will, or by his acts, and whether the new application is substantially for the same invention which was originally claimed. If the two applications are found to be continuous, and it has been therefore proved that the delay in making the new application, after the rejection of the first, has not been unreasonable,
The invention of Weston has been of great utility and has gone into extensive use. The defendants have recently engaged in the manufacture of pulleys, and were early warned of the consequences of infringement. There seems to be no equitable reason why a preliminary injunction should be refused. The motion for a preliminary injunction should be granted.
