International Shoe Mach. Corp. v. United Shoe Mach. Corp.

1 Citing case

  1. Hughes Aircraft Co. v. General Instrument Corp.

    275 F. Supp. 961 (D.R.I. 1967)   Cited 9 times

    The plaintiff argues that following the notice of infringement, the defendant denied infringing Barnes patent and so that patent was not named in the original suit but that after discovery had convinced plaintiff that infringement was in fact taking place, it was added by an amended complaint filed January 15, 1964. The defendant cites International Shoe Machine Corporation v. United Shoe Machine Corporation (D.Mass. 1965) 242 F. Supp. 765; Smith v. Sinclair Refining Company, 2 Cir., 257 F.2d 328. Here there was a fourteen year delay in taking any steps to enforce the patent rights.
