Apple Sued for Security-Patent Infringement by Intertrust

Intertrust Technologies Corp., a developer of digital rights management software jointly owned by Sony Corp. (6758) and Royal Philips (PHIA) Electronics NV, suedApple Inc. (AAPL:US) for allegedly infringing 15 patents related to mobile-device security.

Apple’s iPhone, the iPod touch, iPad product lines, laptop computers, Apple TV and App Store are built on secure computing technologies developed and patented by Intertrust, the company said in a complaint filed today in Oakland, California, federal court. Intertrust has previously sued Microsoft Corp. (MSFT:US) over patents. The software maker settled and licensed the technology in 2004 for $440 million, according to the complaint.

“Apple’s decision to free-ride off Intertrust’s innovations has caused, and continues to cause, substantial harm to Intertrust,” according to the complaint.
