Trials and Appeals in 2015
  • Dataquill Limited v. ZTE USA, Inc.(E.D. Tex): On June 18, 2015, a jury in Marshall returned a verdict in favor of Dataquill Limited on patent claims asserted against ZTE USA (the fourth largest smartphone manufacturer in the U.S.). (Other cases against Apple and Huawei were resolved before trial.) The Dataquill patents concern smartphone technology, and were asserted against ZTE’s Android smartphones. The jury found that all asserted claims were valid and infringed, and awarded a significant amount. This was the twelveth largest verdict in Texas for 2015 and the fifty-ninth largest nationally, according to VerdictSearch. The HPC team representing Dataquill included Les Payne, Nate Davis, and Blaine Larson. HPC’s team worked with attorneys from Susman Godfrey, including Parker C. Folse and Joseph S. Grinstein, as well as Johnny Ward of Ward & Smith Law Firm.
  • Commil USA, LLC v. Cisco Systems, Inc.(Supreme Court of the United States): On May 26, 2015, the Supreme Court issued a 6-2 decision in favor of Commil. The trial is described further below under Trials in 2011. In this landmark decision, the Supreme Court held that an accused infringer’s good faith belief in patent invalidity is not a defense to inducing infringement.
Appeals in 2014
  • Two-Way Media, LLC v. AT&T Inc., et. al.(Federal Circuit Court of Appeals): On March 19, 2015, the Federal Circuit affirmed a significant judgment in favor of Two-Way Media against AT&T, which is described further below under Trials in 2013. Mr. Payne argued for Two-Way Media before the Federal Circuit in December 2014.
Trials in 2013
  • Two-Way Media LLC v. AT&T Inc. et al.(W.D. Tex.): On March 20, 2013, a jury in San Antonio returned a verdict in favor of Two-Way Media LLC, a company based in Colorado, on patent claims asserted against several AT&T entities and its related regional carriers. The TWM patents concern audio and video streaming, and were asserted against AT&T’s U-verse television service (which employs Microsoft’s Mediaroom software). The jury found that AT&T infringed the patent claims under the doctrine of equivalents. The jury further found that AT&T had not proven the patent claims invalid, and awarded a substantial amount in damages. This was the seventh largest verdict in Texas for 2013, according to VerdictSearch. The Court entered a Final Judgment in favor of Two-Way Media. The HPC team representing Two-Way Media included Mike Heim, Les Payne, and Micah Howe. The HPC team worked with attorneys from Susman Godfrey (including Parker Folse and Max Tribble).
Trials in 2012
  • PACT XPP technologies, AG v. Xilinx, Inc. and Avnet, Inc.(E.D. Tex.): On May 18, 2012, a jury in the Eastern District of Texas, Marshall Division, returned a verdict finding that two patents held by PACT were valid and were infringed by Xilinx and Avnet. The jury further found that Xilinx’s infringement was willful, and it awarded a significant amount in damages to PACT. This was the 18th largest verdict in Texas for 2012, according to VerdictSearch.
Trials in 2011
  • Fractus, S.A. v. Samsung Electronics Co., Ltd. et al.(E.D. Tex.): On May 23, 2011, a jury in Tyler returned a verdict in favor of Fractus, S.A., an antenna company based in Barcelona, Spain, on all trial claims asserted against Samsung. The claims were spread across four related patents in Fractus’ Multilevel Patent family, generally covering multiband antennas used in portable communication devices, such as cell phones. The jury found that Samsung infringed the claims literally and under the doctrine of equivalents, as well as finding Samsung’s infringement willful. After finding that Samsung had not proven the patent claims invalid, the jury awarded a significant verdict in favor of Fractus, S.A. This was the tenth largest jury verdict in Texas for 2011, according to VerdictSearch. The HPC team representing Fractus included Michael Heim, Les Payne, and Micah Howe. The HPC team worked seamlessly with attorneys from Susman Godfrey (including Max Tribble, Justin Nelson, and Victoria Cook) and Ward & Smith (Johnny Ward) to produce this result. Prior to trial, the Fractus legal team also assisted in licensing the Fractus patent portfolio to other third parties.
  • Commil, USA v. Cisco Systems, Inc.(E.D. Tex.): On April 8, 2011, a jury in Marshall, Texas returned a verdict in favor of Commil USA, LLC on all infringement claims asserted against Cisco Systems, Inc. The jury, which deliberated less than two hours, decided Cisco induced infringement on a patent for wireless technology developed by three Israeli engineers and awarded Commil a significant amount. This was the seventh largest jury verdict in Texas for 2011, according to VerdictSearch. Commil had purchased the infringed patent in 2006 for $400,000.00. Mr. Payne represented Commil at trial and worked with trial counsel from Sayles Werbner (Mark Werbner & Dick Sayles) to achieve this result.
Other Representative Cases
  • MicroUnity Systems Engineering, Inc. v. Intel & Dell: MicroUnity filed suit against Intel Corporation, alleging that Intel’s Pentium III, Pentium 4, and Pentium M processors infringed MicroUnity’s patents covering its “mediaprocessor” technology.

Lenovo (United States) Inc. et al: In 2011 and 2012, Mr. Payne and other attorneys from HPC represented the Commonwealth Scientific and Industrial Research Organisation, Australia’s national science agency, in a series of patent litigation suits involving wireless local area networking technology. These cases were settled shortly before trial on terms that were very favorable to CSIRO.
