Apple, MS, LG being sued
Apple, Microsoft, LG, and 20 other companies are being sued for patent infringement by Tsera, who claims to have invented the touch pad used in devices such as the iPod classic, the Zune, and the Chocolate VX8500. The patent was first filed in 1999 by Chuang Li and was granted in 2003, following the release of the second generation iPod classic. The patent's wording could lead to the case being thrown out as it describes the technology differently from how the iPod works. The patent states that "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."
Tsera's complaint singles out Apple, suggesting the company knew of the patent since September of 2004. The firm is seeking "enhanced damages, up to treble damages," while the other companies being sued are being asked for standard damages to be returned. The lawsuit also demands the defendants "pay a compulsory future royalty" to continue using the touch pad in their devices.
Apple has previously faced two other lawsuits claiming patent infringement, though neither of the cases involved the touch pad.
