Interstate Folding Box Co. v. Empire Box Corp.

SLICK, District Judge.

This is a suit for infringement of patent No. 1,461,967, a process patent. The original bill charged infringement of several claims of patent No. 1,461,966, issued for a machine. The two patents, one on a machine and one for a process, were issued simultaneously. The machine patent, No. 1,461,966, has been dismissed out of the case, leaving only the process patent in issue.

Defendant claims this patent is invalid and void for the reason that it does not set up a patentable process, but only statements of a function of the automatic machine covered by patent No. 1,461,966.…
