26 F.2d 722 | S.D.N.Y. | 1928
These patents have been so often adjudged valid that it may well be said that the point has been reached, if not already passed, where the concordance of opinion sustaining them has become a controlling authority. Mast, Foos & Co. v. Stover Mfg. Co., 177 U. S. 485, 20 S. Ct. 708, 44 L. Ed. 856. Finding no reason to believe that the many decisions which have already been rendered upon full considera
There remains only the question of infringement. It appears that the defendant has sold a grease gun with Gullborg and Zerk couplers, which it has purchased in the open market. There can be no doubt that these couplers were sold with its grease gun so that the purchasers might, as they undoubtedly did, use the equipment in connection with Gullborg and Zerk fittings or nipples. When this is done, the patented combination of Gullborg or of Zerk, as the case may be, is completed. This constitutes infringement, and to such infringement the defendant contributes by furnishing the gun and the coupler for this purpose. Leeds & Catlin v. Victor Talk. Mach. Co., 213 U. S. 325, 29 S. Ct. 503, 53 L. Ed. 816; Lyman Mfg. Co. v. Bassick Mfg. Co. (C. C. A.) 18 F.(2d) 29; Bassick Mfg. Co. v. Larkin Automotive Parts Co. (D. C.) 19 F.(2d) 939, affirmed (C. C. A.) 19 F.(2d) 944; Bassick Mfg. Co. v. Ready Auto Supply Co., Inc. (D. C.) 22 F. (2d) 331.
The defendant has complained of the plaintiff’s assertion and enforcement of its patent rights as an unfair interference with its trade. The plaintiff’s conduct has been vigorous in this regard, but has not exceeded the bounds of good faith in the assertion and enforcement of rights fairly claimed under its patents. This disposes of the defense of unclean hands, and of defendant’s counter motion for a preliminary injunction based on unfair competition. There can be no preliminary injunction upon defendant’s motion because of plaintiff’s alleged infringement of the Wilson patent, No. 988,422. This patent does not appear to have been adjudicated.
Plaintiff’s motion granted. Defendant’s motion denied.
