  • Texas State Bar
  • US Patent and Trademark Attorney
  • Major mobile device chip provider in defending a seven-patent investigation brought at the International Trade Commission (ITC), where Complainant alleged that the patents covered various aspects of graphical processing units (GPUs) contained within accused smartphones. After accelerated discovery and a multi-day evidentiary hearing, the Administrative Law Judge (ALJ) determined that no violation of section 337 had been established. Over Complainant's objections, the full ITC declined to review the ALJ's initial determination of no violation. Complainant appealed to the Federal Circuit, but subsequently dismissed the appeal as well as a parallel district court action.
  • Wireless technology company in an arbitration action filed by its licensee, which disputed whether certain events triggered its royalty payment obligations and claimed that differences between its and the third party's products precluded the triggering of its payment obligations. Following the prehearing submission of multiple technical expert witness statements, a two-week arbitration hearing and post-hearing briefing, the Tribunal found obligations were triggered and established royalty rates applicable to licensee's covered products.
  • Major mobile device chip provider in defending a four-patent investigation brought at the ITC, where Complainant alleged that three patents covered various aspects of graphical processing units (GPUs) and one patent covered DDR memory controllers. After the claim construction hearing, the case favorably settled.
  • Leading e-commerce companies accused of infringing a parametric search patent. Transferred the case from the Western District of Wisconsin to the Northern District of California, where the team won several significant discovery battles that shaped the requirements of the Local Patent Rules. Later obtained summary judgment that the asserted claims were obvious, which the Federal Circuit affirmed.
  • Point-of-sale software company in the Eastern District of Texas accused of infringing three patents related to wireless handheld devices and web page communications. After a five-day trial, the jury found our clients did not infringe and that the asserted claims were anticipated and obvious.
  • Leading Internet, eCommerce, information and analytics companies in the Western District of Texas, where plaintiff alleged that their search engines and data retrieval systems violated its patent. Following extensive briefing and discovery, a full-day technical tutorial and a full-day claim construction hearing, all asserted claims were found to be indefinite and, therefore, invalid as a matter of law.
  • Represented information and analytics companies in the Northern District of California accused of infringing patented method and system for storing and presenting medical data. The court granted Defendants' motion to dismiss, finding that the claims of the asserted patent were ineligible for patent protection and thus invalid.
  • Telecommunications company accused of infringing four patents concerning streaming Internet technology and satellite delivery technology; following the filing of a motion for summary judgment of invalidity, the matter was favorably settled.
