1Opinion of the Court
PHILLIPS, Circuit Judge.
Plaintiff-appellant (Erickson) is the owner of U. S. Patent No. 3,035,845, granted May 22, 1962, known as the Benjamin patent. This action was filed against defendant-appellee (Balas) for infringement of Claim 3 of this patent. Balas denied infringement and filed a counterclaim for declaratory judgment of invalidity and non-infringement. District Judge Girard E. Kalbfleisch held that Claim 3 of the Benjamin patent is invalid for obviousness and lack of novelty. We affirm.
The findings of fact and conclusions of law of the District Court are published at 277 F.Supp. 226.
