LEVIN H. CAMPBELL, Circuit Judge.
Avant Incorporated sued Polaroid Corporation for infringement of patent No. 3,679,512 (the '512 patent) issued to Avant as assignee of the inventor. The patent disclosed an allegedly novel plastic envelope which, after the insertion of a data card, is to be subjected to heat and pressure in order to produce a laminated data card. The district court found for Polaroid on the latter’s counterclaim which asserted that the patent was invalid for obviousness under 35 U.S.C. § 103. Avant Inc. v. Polaroid Corp., 441 F.Supp. 898 (D.Mass.1977). Avant appeals.
