Representative Matters

Acantha LLC v. DePuy Synthes
Mr. Stewart served as trial 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. Stewart’s client. Mr. Stewart continued to represent Acantha in subsequent litigation against NuVasive, Inc. and Stryker Corporation, and in further licensing of Acantha’s intellectual property.

REM Holdings 3, LLC, et al. v. Square, Inc., et al.
Mr. Stewart represented university professor Dr. Robert Morley Jr. and his company, REM Holdings, in Dr. Morley’s claims over the founding of mobile payments company Square. The parties entered into a mutually agreeable settlement in 2016. Mr. Stewart continued to represent Dr. Morley in connection with his patents covering mobile payments technology, including arguing on REM’s behalf before the U.S. Court of Appeals for the Federal Circuit.

VirnetX, Inc. v. Apple, Inc.
Mr. Stewart has represented VirnetX, including as trial counsel, in the company’s patent infringement litigation against Apple over the infringement of VirnetX’s network security patents by Apple’s FaceTime, iMessage, and VPN On Demand features.
