PixArt announces that it owns a total of 626 granted optical navigation-related patents over the world. The granted patents cover circuits, algorithms, system application, package, optical structures, and semiconductor process, which can be widely applied to the products such as optical mouse and optical finger mouse.
Part of these patents were received through a patent deal with Avago at the end of 2011. Avago sold some optical navigation patents and exclusive licenses of its optical navigation patents to PixArt. Under this agreement PixArt also has the right to sue anyone who infringes these patents.
