The ruling, discovered by PSP Fanboy, ends a lawsuit filed two years ago by Agere. The firm is now a subsidiary of a company called LSI, "a leading provider of innovative silicon, systems and software technologies that enable products which seamlessly bring people, information and digital content together."

A jury ruled that the patent infringement was willful, which likely contributed to the total amount Sony is ordered pay.

Sony, like other large-scale game companies, was also recently hit with a patent claim for the PlayStation 3's Blu-Ray capability. In 2007, the company won a dismissal in a Blu-Ray-related suit and settled with Immersion, a force-feedback developer.
