Kazuhiro Okada, inventor of 6,512,364, assigned the patent to Saitama, Japan-based Wacoh last month. '364 claims methods for testing sensors. Wednesday, Wacoh filed a complaint in the Western District of Wisconsin against auto makers GM, Ford, Chrysler, BMW, Mercedes-Benz, Volkswagen, Honda, Mazda, and Suzuki. Toyota is notable by its absence. The prayer for relief is "no less than a reasonable royalty."

Okada is named on quite a few US patents on airbag sensors. An article here http://www.virtusensors.com/user/news_detail.php?id=11 says that he is the president of Wacoh. "We have licensed multi-axis accelerometer patents to a number of Japanese and one foreign company, and the licensing revenues are expected to increase gradually. We have obtained about 180 patents and maintain 150 of them."
