In today's economy, it is inevitable that any successful product will result in the filing of at least one lawsuit for patent infringement. Nintendo similarly appears to have its first lawsuit based on the Wii. Interlink Electronics, Inc., owner of U.S. Patent. No. 6,850,221, filed a lawsuit against Nintendo on December 4, 2006, in the United States District Court for the District of Delaware. The lawsuit alleges patent infringement based on Nintendo's Wii controller.
