Page v. Buckley

67 F. 142 | U.S. Circuit Court for the Northern District of Illnois | 1895

GROSSCUP, District Judge.

There has been no adjudication of the validity of complainant’s patent outside of the finding of the patent office in an interference hearing, and nothing that amounts to public acquiescence. The decision of the patent office determined that the complainant’s and defendant’s inventions were the same, and that complainant’s, in point of time, was prior; but its validity, in view of the state of the art, was not inquired into, much less determined. The issuance of a patent, in this circuit at least, is not sufficient prima facie evidence of the novelty of the invention as justifies an injunction.

Neither is defendant, by the fact of having presented a claim for a patent for the same invention, barred from denying novelty. The right against monopoly is a general right, in which defendant shares, until it is adjudicated in a real contest that the invention has not been anticipated and the patent is in other respects valid.

Injunction denied,
