Dallas-based intellectual property and business litigation law firm Caldwell Cassady & Curry won a unanimous $502.6 million patent infringement verdict last week for Nevada-based VirnetX Inc. against Apple Inc. in the U.S. District Court for the Eastern District of Texas, Tyler Division.

The seven-day trial focused on four VirnetX patents (U.S. Patent Nos. 6,502,135; 7,490,151; 7,418,504; and 7,921,211). Jurors determined Apple’s attempted redesign fell short following a 2016 trial that ended with a separate jury finding that the company infringed VirnetX’s patents with the popular Facetime and VPN on Demand features used in the iPhone and other Apple products.

VirnetX was represented at trial by Caldwell Cassady & Curry name principals Brad Caldwell, Jason Cassady and Austin Curry, along with firm associate Chris Stewart and Ward, Smith & Hill, PLLC name partner Johnny Ward.

In the next phase of the trial, the same jury will be asked to determine whether Apple willfully infringed VirnetX’s patents. A decision in favor of VirnetX could leave Apple liable for increased damages.

This marks the fourth consecutive trial Caldwell Cassady & Curry attorneys have won on behalf of VirnetX during the company’s continuing patent litigation against Apple. The firm’s verdicts have netted its client nearly $1.5 billion in damages. Six months before the aforementioned 2016 verdict, the firm helped VirnetX win a $625.6 million award against Apple in another Eastern District case. In 2012, lawyers from the firm won VirnetX’s first victory against Apple when a separate jury awarded a $368 million verdict against Apple.

In August 2017, Leaders In The Law reported on Ward Smith & Hill’s $21 million patent infringement verdict on behalf of an Israeli technology and defense company.
