Apple: VirnetX can't raise willfulness in patent saga now

VirnetX, an Internet security software and technology company, can’t claim in a retrial that Apple willfully infringed patents for FaceTime and other technologies, after the patent-holding company specifically disavowed that allegation in earlier court filings, Apple told a Texas federal judge on Wednesday.

In January 2014, VirnetX filed a motion with the U.S. District Court for the Eastern District of Texas seeking to supplement its infringement contentions against Apple, the defendant in a patent infringement lawsuit. And in May 2016 the company asked a Texas court to order Apple to stop providing its FaceTime and Messages features to customers, following the patent troll’s early court victory regarding patent infringement.

The motion alleged that Apple products, including products containing the redesigned VPN On Demand and Per App VPN features implemented in Apple’s iOS 7, continue to infringe VirnetX’s patented inventions. Some of the currently accused products in this lawsuit include the iPhone 5, iPod touch (fifth generation), iPad (fourth generation), iPad mini, and certain Macs.

However, in September 2014, a federal appeals court tossed out a $368 million jury award for patent infringement that VirnetX Holding won against Apple in 2012. The U.S. Court of Appeals for the Federal Circuit, a specialized Washington-based court that handles patent appeals, ruled the verdict was "tainted" by erroneous jury instructions in the case. This sent the case back to a trial court.
