A federal jury in Texas on Friday ordered Apple to pay more than $302 million in damages for using VirnetX Holding Corp's internet security technology without permission in features including its FaceTime video conferencing application. The verdict came in a new trial in Tyler, Texas that had been ordered by the judge in the case, Robert Schroeder, who last August threw out VirnetX's $625.6 million win over Apple from a previous trial because he said jurors in that case may have been confused.

The case began in 2010 when Nevada-based patent licensor VirnetX filed suit in the Eastern District of Texas federal court, claiming infringement of four patents for secure networks, known as virtual private networks, and secure communications links.

A jury in 2012 awarded $368.2 million in damages, but the U.S. Court of Appeals for the Federal Circuit in Washington, D.C., partly overturned that verdict.

On remand, VirnetX's two suits were combined, and in February, a jury returned with an even bigger verdict, $625.6 million, one of the highest ever in a U.S. patent case.

However, Schroeder later voided the result, saying that the repeated references to the earlier case could have confused jurors and were unfair to Apple.

Apple will also have to contend with the trial in a second lawsuit VirnetX filed against Apple over newer versions of Apple security features, as well as its iMessage application.
