Siemens-Lungren Co. v. Hatch
Opinion of the Court
This is a motion for an interlocutory injunction to restrain the respondents from infringing letters patent No. 282,387, granted July 31,1883, to Andrew P. Lipsey, for gas-burner; and No. 299,660, granted June 3, 1884, to Andrew P. Lipsey, for gas-burner. Several questions arise on the affidavits, which I do not find it necessary to decide, because, in my view, the present motion must be disposed of on a single consideration, which is as follows: It is admitted that the patents in suit are anticipated by patents to Christian Westphal, in the German empire, May 9,1882, and numbered 21,809; and in Prance, March 2, 1882, and numbered 147,691, — unless the court shall find that the invention of Lipsey was made at a certain time earlier than the date of his application for a patent. The complainant for proof of this point relies on the affidavit of Lipsey and on the finding of the examiner of interferences in an interference between the application for letters patent No. 299,660, and the application of J. Gardner Sanderson, upon which letters patent were granted to said Sanderson, January 29, 1884, — No. 292,766. The affidavit of Lipsey uses only these words: “I completed the inventions which are the subject of those patents in March, 1881, having first conceived of them as early as July, 1877.” The finding of the examiner is that “upon the testimony adduced-in behalf of Lipsey, it appears that he conceived of this improvement in March, 1881, and immediately made sketches illustrating the arrangement and disposition of parts in his proposed lamp.” Either of the dates here given would, it appears, be sufficiently early to negative the claim of anticipation. It is undoubtedly true, as the respondent contends, that the decision of the examiner is by no means entitled to the weight which would be given to a final adjudication by a court of justice, but I am not disposed to say that it should be entirely disregarded. It is a final decision of a tribunal competent to hear and decide the question of priority of invention, and such a decision might in some cases be entitled to much weight. But not even a decision of a court would be conclusive; and still more must this decision be scrutinized in order to see whether the ground and manner of the decision are such that this court may with a good conscience take the finding as establishing the facts therein set forth.
