Intertrust Sues Apple, Charging Patent Violations

Intertrust, a company that nabbed a huge settlement over patents in a lawsuit with Microsoft nearly a decade ago, has turned its focus to Apple, suing the technology giant on Wednesday and charging infringements of its security and content protection patents.

Intertrust, which is largely owned by Sony and Philips, sued Apple in Federal District Court in the Northern District of California, claiming it violated more than a dozen patents throughout its product lines, including the iPhone, Apple TV, iPad, iPod and Macintosh computers. Intertrust is best known as an early developer of digital rights management technologies — software that is used to prevent unauthorized access to music, movies, apps and other forms of electronic content
