Brown v. Piper

APPEAL from the Circuit Court of the United States for the District of Massachusetts.

Piper filed a bill to enjoin Brown and Seavey from infringing two patents, one of which, not being insisted on at the hearing, need not be considered. The other-No. 732, dated March 19, 1861 makes claim as follows:--

'Preserving fish and other articles in a close chamber by means of a freezing mixture, having no contact with the atmosphere of the preserving chamber.'

The defendants by their answer, among other objections not necessary to be mentioned, denied the novelty of the alleged invention.

The court below rendered a decree sustaining the validity of the patent, and perpetually enjoined the defendants from using or employing the invention therein described. They bring this appeal.

Mr. George Gifford and Mr. Edward Avery for appellants.

Mr. Causten Browne for appellee.

MR. JUSTICE SWAYNE delivered the opinion of the court.
