Summary: Wing Shing obtained a design patented on a coffeemaker, which it then licensed to Sunbeam, after Sunbeam had required certain astethetic changes to the coffeemaker. Sunbeam later had Simatelex produce additional coffeemakers for Sunbeam. After a dramatic reduction in volume, Wing Shing sued Simatelex for patent infringement. The C.A.F.C affirmed that Sunbeam was not a co-inventor and Wing Shing was not barred by the doctorine of equitable esttople. See also, MP3: Sunbeam v. Wing Shing (Fed.
