Representative Matters


Match Group, LLC v. Bumble Trading, Inc.
Mr. Pearson represents Match Group, owner of numerous popular online dating brands including the iconic Tinder application, in a highly publicized intellectual property and business dispute with competitor Bumble in the U.S. District Court for the Western District of Texas.
Acantha LLC v DePuy Synthes
Mr. Pearson served as counsel for Acantha LLP in a patent infringement lawsuit against medical device manufacturer DePuy Synthes, a subsidiary of healthcare giant Johnson & Johnson. DePuy was sued based on its infringement of an Acantha patent that covers an orthopedic implant assembly used in surgical procedures. Following the August 2018 trial in the U.S. District Court for the Eastern District of Wisconsin, a jury of five women and three men delivered a unanimous $8.2 million verdict in favor of Mr. Pearson’s client.

VirnetX, Inc. v. Apple, Inc.
Mr. Pearson represents VirnetX in the company’s ongoing litigation against Apple for infringement of VirnetX’s network security patents by Apple’s FaceTime, iMessage, and VPN On Demand features. In the first trial against Apple in 2012, a jury in the U.S. District Court for the Eastern District of Texas found VirnetX’s patents valid and awarded a $368 million verdict based on Apple’s infringement.

After the case was sent back for a new trial on damages, it was consolidated with a subsequent lawsuit covering newer products that Apple marketed after the first trial. In the consolidated trial, Mr. Pearson and other attorneys at Caldwell Cassady & Curry won again; securing a $625 million verdict for VirnetX in February 2016 after another Eastern District jury found that Apple continued to infringe VirnetX’s patents following the first trial. The jury also found that Apple’s infringement was willful regarding FaceTime and VPN on Demand.

The court later vacated its order to consolidate the matters and set the cases covering newer and older products for two separate jury trials.

In the first new trial heard in October 2016, Mr. Pearson helped VirnetX win once again, securing a $302 million verdict against Apple. The verdict was entered as a $439.7 million judgment in September 2017.

In the second new trial heard in April 2018, a different Eastern District jury awarded a unanimous verdict of $502.6 million in favor of VirnetX after finding Apple’s infringement was willful. The entire verdict amount was entered as a judgment in August 2018.

VirnetX, Inc. v. Microsoft Corp.
Daniel represented VirnetX in its second patent infringement action against Microsoft involving virtual private network technology. In 2011, a jury awarded VirnetX $105 million in its verdict and found that Microsoft’s infringement had been willful. The case settled after VirnetX moved for a permanent injunction. Following Microsoft’s acquisition of Skype, VirnetX was again forced to defend its patent rights. Daniel worked on all aspects of this case up until the time VirnetX obtained a favorable settlement from Microsoft.
