Goodyear Tire & Rubber Co. v. Ray-o-Vac Co.
United States Supreme Court
321 U.S. 275, 64 S. Ct. 593, 88 L. Ed. 721 (1944)
- Written by Eric Miller, JD
Facts
A patent was issued for a leakproof dry cell for use as a flashlight battery (the Anthony patent). Prior to the invention, flashlight batteries used paper coating, which was prone to leakage and swelling. The Anthony patent was assigned to Ray-o-Vac Co. (plaintiff), which successfully sold the leakproof cell to consumers. Later, Ray-o-Vac sued Goodyear Tire & Rubber Co. (defendant) for infringement. Although it was argued that the patent should be invalidated on the ground of obviousness, the federal district court and the court of appeals found the patent to be valid and infringed. The case was appealed to the United States Supreme Court.
