247 F. 487 | 2d Cir. | 1917
(after stating the facts as above). The first question raised is as to the propriety of a proceeding to punish for contempt, where the defendants are manufacturing under a patent of their own issued after the decree, and where the decree itself was entered by consent. We do not know the composition of the original halvah found to be within the patent on March 5, 1915, but on principle we cannot see how the fact that, the defendants are manufacturing under a new patent has any bearing upon this issue. The Patent Office does not and cannot, in granting patents, regard questions of infringement; they are concerned only with conflicting claims. Were it not so, they would have to determine whether every improvement of an existing patent was or was not an infringement, which, of course, they could not do. It is undoubtedly a fact that there is much authority in the books for the proposition that the defendant’s patent creates a presumption of noninfringement; but we observe that the Sixth Circuit has declined to follow the rule (General Electric Co. v. Electric Cont. & Mfg. Co., 243 Fed. 188, 193,-C. C. A.-), and certainly this is the only tenable principle, however strongly the contrary may be fixed in the books.
With the modifications above indicated, the decree is affirmed, without costs.
