204 F. 790 | 2d Cir. | 1913
The firm Fishel, Nessler & Co. was composed of the patentee, Henry W. Fishel, and Theodore H. Fishel. This firm and the individual members thereof went into bankruptcy and all their property passed to their trustee. The latter sold these two patents in due course to one Swartz. Subsequently the complain
At the trial the court directed that the testimony offered by defendants be limited to the issue of infringement “upon the ground that the defendants were estopped from denying the validity of the patents.” The court did not write any opinion and the defendant appellants apparently assume that it held that the estoppel was created by the bankruptcy sale, in favor of Swartz the purchaser and of his subsequent assignees. It is a familiar principle that a patentee who transfers his patent to some one else cannot thereafter, when sued by such transferee for infringement, assert that the patent is invalid, and the main argument in the case is directed to the question whether this principle will apply when the transfer is not a voluntary one; certainly the bankruptcy sale was not the voluntary act of the owner of the patent.
The decree is reversed, without costs of this court, and cause remanded, with instructions to decree in favor of defendants on design patent Ño. 37,055, and in favor of complainant on patent No. 884,979, without costs to either side.
