Lyon v. Bausch & Lomb Optical Co., 224 F.2d 530, 106 U.S.P.Q. 1

Facts

This case involves a patent infringement action concerning Patent No. 2,398,382, which pertains to a method for applying hard, durable, low reflecting films of inorganic salts on optical surfaces. The plaintiff, Lyon, was granted the patent in 1946, and the District Court initially held all claims valid. However, the defendant appealed, contesting the validity of certain claims. The Court of Appeals affirmed the validity of claims 3, 8, and 9, but reversed the lower court's decision regarding claims 1, 2, 4, and 5, citing inadequate support in the patent specifications.
