On August 30, 2010, a San Diego based gaming technology company by the legal name of Tritton Tech of Texas, LLC and known as Tritton Technologies, has filed a patent infringement lawsuit against Nintendo and Apple Inc., in the District Court for the Eastern District of Texas. The company claims that Apple's iPhone 4 violates their 1993 patent which covers accelerometers for sensing linear translation along three axes of a Cartesian coordinate system and three angular rate sensors for sensing angular rotation about the three axes.
