According to a Bloomberg report, well-known motherboard and chipset manufacturer Via has filed a patent infringement lawsuit against Apple. Filed in Delaware Federal court, the complaint accuses Apple of infringing three US patents that cover microprocessor technology used in smartphones and tablets. Presumably, this lawsuit is targeting Apple's A4 and A5 processor used in the iPhone 4, iPad and the iPod touch. The Taiwanese manufacturer is asking for an injunction against Apple products containing these microprocessors and a jury trial. Apple, as expected, has not commented on this latest lawsuit.
