Coffin v. Ogden
APPEAL from the Circuit Court for the Southern District of New York, in which court Coffin filed a bill against Ogden et al. to enjoin them from making door locks of a certain kind, the exclusive right to make which he alleged belonged by the assignment of a patent right to him.
The case was one chiefly of fact, involving the question of priority of invention. The court below was of the opinion that the complainant, or rather the person under assignment of whose patent he claimed and was working, had been anticipated in his invention; and dismissed the bill. From that decree the defendants took this appeal.
Mr. George Gifford, for the appellant; Mr. B. F. Thurston, contra.
Mr. Justice SWAYNE stated the case, recited the evidence, and delivered the opinion of the court.
