Doctrine of Equivalence
United States Court of Appeals, Federal Circuit
Jerome H. Lemelson v. General Mills, Inc.
No. 90-1359
June 30, 1992
United States District Court for Northern District of Illinois found in favor of plaintiff.
The United States Court of Appeals reversed.
Lemelson issued a patent for "Toy Track and Vehicle Therefor" (June 24, 1969).
Matel (Defendent-Appellant) began independent track development (1967). Researched the prior art (Lemelson's patent did not yet exist) and concluded that a few features of the track may be patentable. Patented features of Hot Wheels but not the actual track.
