Electric Storage Battery Co. v. Shimadzu
United States Supreme Court
307 U.S. 5 (1939)
Genzo Shimadzu (plaintiff), a Japanese citizen and resident, sued Electric Storage (defendant) for infringement of three patents, two claiming methods and the third claiming an apparatus, all generally related to powder used to make a component of batteries. The three patents were issued between 1922 and 1926. Electric Storage began to use the patented apparatus in 1921. Shimadzu was able to prove at trial that he had invented the subject of the patents as early as 1919.
