The Eastern District Court of Texas in Tyler, Texas, on Wednesday, March 21, 2018. 

A federal jury awarded internet security software company VirnetX $502.6 million last week. The jury found Apple Inc. willfully infringed on four patents used for VPN on Demand and Facetime in Apple products.

The case was heard in the U.S. District Court for the Eastern District of Texas, Tyler Division. 

The liability and damages verdict was returned on April 10 at the end of a seven-day trial and the willful infringement finding was returned the following day.

The claim from Nov. 6, 2012 said Apple, directly and through subsidiaries or intermediaries including distributors, retailers, and others purposefully and voluntarily placed one or more of its infringing products or services into the stream of commerce with the expectation that they will be purchased and used by consumers in the Eastern District of Texas.

The findings show Apple willfully infringed on four VirnetX communications patents.

This was the third jury verdict in the past two years secured for VirnetX in its long-running legal battle with Apple.
