As seen in this TechFlash article, Microsoft has launched a patent suit against TomTom, a seller of (Linux-based) navigation devices. "It's believed to be the first time Microsoft has filed a patent suit over Linux, after claiming for years that elements of the open-source operating system violate its patents. However, Microsoft says open-source software is not the intended focal point of the action." The lawsuit focusses on several navigation techniques, and includes a few patents related to Linux. LWN lists the individual patents in question.
