Representative Matters

Cellular Communications Equipment LLC v. Apple Inc.
Mr. Cassady represented Cellular Communications Equipment LLC in a patent infringement lawsuit against Apple Inc. over a network technology patent. Following a trial heard in September 2016 in the U.S. District Court for the Eastern District of Texas, jurors found Apple to be a willful infringer and awarded a $22 million verdict in favor of CCE. The award represented a running royalty on Apple’s infringement through March 2016.

Smartflash Litigation
Mr. Cassady represents Smartflash in its litigation against Apple, Samsung, Google, and other device manufacturers for infringement of Smartflash’s patents that cover data storage and access systems used by Apple’s iTunes and App Stores and Google Play. Mr. Cassady was trial counsel for Smartflash during its case against Apple. The jury returned a verdict of $532,900,000 and found Apple’s infringement to be willful.

VirnetX, Inc. v. Apple Inc.
Mr. Cassady represents VirnetX as co-lead trial counsel 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. Cassady 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. Cassady 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 v Microsoft
As lead trial counsel, Mr. Cassady represented VirnetX in its multi staged patent litigation and licensing with Microsoft. In 2011, a jury awarded VirnetX $105,000,000 in its verdict and found that Microsoft’s infringement had been willful. That case settled after VirnetX moved for a permanent injunction. In subsequent litigation involving additional infringement assertions, Microsoft settled before trial.

Bedrock Computer Techs. v. Google Inc.
Mr. Cassady, as trial counsel, represented Bedrock in a suit filed against Google for patent infringement involving methods for efficiently removing expired data from information storage and retrieval systems. The case settled shortly after the jury awarded $5 million in favor of Bedrock.

VirnetX v. Mitel et al
As lead counsel, Mr. Cassady represented VirnetX in matters against Siemens, Mitel, and Avaya regarding security technology for IP phones and other IP related communications. Siemens, Mitel, and Avaya settled litigation involving patent infringement before trial.

Dr. Robert Morley v. Square Inc.
Mr. Cassady represents Dr. Morley in his suit against Square, Inc., Jack Dorsey, and Jim McKelvey for patent infringement and breach of joint-venture and fiduciary duty, misappropriation of trade secrets, and for exclusion of Dr. Morley from Square. Dr. Morley revolutionized the mobile payment industry with his invention of the Square card reader. A trial in the Eastern District of Missouri is scheduled for mid-2016.

Anascape, Ltd. v Nintendo et al.
Mr. Cassady represented Anascape in its patent infringement lawsuit against Microsoft and Nintendo involving video game controller technology. After a two week trial in the Eastern District of Texas, Anascape obtained a jury verdict against Nintendo. Microsoft and Anascape reached a confidential settlement on the eve of trial.

Opti Inc. v. Apple Inc.
Mr. Cassady, as trial counsel, represented Opti, Inc. in a patent infringement suit against Apple regarding its patent regarding a computer operation that enables a “pre-snooping” function designed to allow for the more efficient transfer of data.

Mr. Cassady and others from McKool Smith won a substantial jury verdict on behalf of Medtronic in a patent infringement lawsuit alleging infringement of Medtronic patents covering the design of balloon angioplasty catheters and polymers used to build those catheters.
