Touchpad Patent Holder Tsera Sues Just About Everyone

eldavojohn writes "Okay, well, maybe not everyone but more than twenty companies (including Apple, Qualcomm, Motorola and Microsoft) are being sued for a generic patent that reads: 'Apparatus and methods for controlling a portable electronic device, such as an MP3 player; portable radio, voice recorder, or portable CD player are disclosed. A touchpad is mounted on the housing of the device, and a user enters commands by tracing patterns with his finger on a surface of the touchpad. No immediate visual feedback is provided as a command pattern is traced, and the user does not need to view the device to enter commands.' Sounds like their may be a few companies using that technology. The suit was filed on July 15th in the favoritest place ever to file patent claim lawsuits: Texas Eastern District Court. It's a pretty classic patent troll; they've been holding this patent since 2003 and they just noticed now that everyone and his dog are using touchpads to control portable electronic devices."
