202 F. 967 | S.D.N.Y. | 1912
This is a suit to enjoin the infringement of two patents, numbered 893,853 and 919,369, issued to Dunn and Eocke, and by them conveyed to the complainant. Dunn, the defendant is one of the original patentees. He therefore is estopped from denying the validity of the patent upon any ground. He is not prevented however, from showing by the condition of the prior art that the patent is a narrow one, for the purpose of determining the question of infringement.
There should be a decree for the complainant as demanded in the bill, with costs.
