“Intertrust Technologies Corp., a Silicon Valley company that was an early pioneer in digital copyright protection, says Apple Inc. is violating its patents,” Don Clark reports for The Wall Street Journal.

“The company on Wednesday said it filed a suit in U.S. District Court in Northern California, alleging that Apple infringed 15 of its products. Intertrust said the suit covers a broad range of Apple products, including the iPhone and iPad, Mac computers and laptops, Apple TV, and services that include iTunes, iCloud and the Apple App Store,” Clark reports. “Intertrust has some influential backers. Sony Corp. and Royal Philips each hold 49.5% stakes in the company, which was publicly held from 1999 to 2003. It also has a track record of successfully enforcing its intellectual property. Microsoft Corp, for example, in 2004 agreed to pay Intertrust $440 million to settle a broad patent infringement suit.”
