Charles E. Phipps

I'll research this attorney's background and practice.

Let me verify the two tracked Samsung cases and any PTAB/IPR history.

Let me confirm Phipps's role in the XiFi and Omni MedSci matters and verify the Repeat Precision outcome.

Charles E. Phipps — patent litigation practice summary

Specialty / focus. Phipps is a Dallas-based IP litigator and USPTO-registered patent attorney whose patent work spans a broad technical range rather than a single niche: wireless/telecommunications (his tracked defense of Samsung in XiFi Networks R&D v. Samsung Electronics concerns multi-link Wi-Fi operation under the IEEE 802.11be "Wi-Fi 7" standard and eleven related patents), wearable optical/physiological sensing devices (Omni MedSci v. Samsung, involving light-source/detector pulse-oximetry-type technology), oilfield tools and drilling equipment (Repeat Precision v. Diamondback), plus banking and financial transaction processing, consumer products, software, chemistry and semiconductor matters. Firm bios describe experience across aerospace, medical devices, pharma, encryption, e-commerce and military applications. His prosecution-side portfolio work has included Technip (energy process technology), Kronos, Echelon, AirBorn and Daiichi Sankyo, consistent with a chemistry/electronics/energy docket.

Side preference. His tracked appearances are 0 plaintiff / 2 defendant, and the two matters on record are both Samsung defense representations. That aligns with a defendant-leaning practice: much of his representative docket is defending operating companies against NPE/PAE suits (Lodsys v. Disney, U.S. Ethernet Innovations v. Xerox, TQP Development v. BB&T — dismissal with prejudice for BB&T, CloudofChange v. NCR, EmeraChem v. Volkswagen, Sycamore IP v. Xtera/Menara). He is, however, not exclusively defense-side: firm bios describe him as counsel for both plaintiffs and defendants, and his most-cited win is as plaintiff's counsel in Repeat Precision, LLC v. Diamondback Industries, Inc. (W.D. Tex., Judge Albright), where the plaintiff obtained a damages award of over $40 million plus a permanent injunction. The firm bio also states he has defeated claims alleging more than $6 billion in damages; the specific matter behind that figure is not identified in the source, so treat it as firm-described rather than independently verified.

Firm context. Phipps is a partner at Troutman Pepper Locke, resident in Dallas, where he is a registered patent attorney. He spent the bulk of his career at Locke Lord (formerly Locke Liddell & Sapp), where he was elevated to partner effective 2003 and served as co-chair of the firm's Intellectual Property Litigation Practice Group; Locke Lord combined with Troutman Pepper in 2025 to form Troutman Pepper Locke. His two tracked matters reflect that transition — the earlier Omni MedSci case is docketed under Locke Lord and the later XiFi case under Troutman Pepper Locke. He is not in-house.

PTAB / IPR experience. His bios consistently list representation in "adversarial proceedings before the U.S. Patent and Trademark Office," and he is a registered patent attorney with a prosecution practice. However, in the XiFi and Omni MedSci matters the parallel IPR/PGR petitions (e.g., PGR2025-00069 and the IPR2025-01203–01209 series against XiFi; PGR2025-00063/64 and IPR2025-01251–01254 against Omni MedSci) show Quinn Emanuel and other counsel of record for Samsung, not Phipps. So while he has USPTO experience, there is no verified indication that he is a regular PTAB practitioner in these tracked cases; that should be confirmed before pitching him as an IPR lead.

Bar / education. J.D., University of Texas School of Law (1995); B.S., Texas A&M University (1992, cum laude). Admitted in Texas (1995), New York (1998), Florida (2022), and before the USPTO; admitted to the U.S. Supreme Court, the Federal Circuit and the Fifth Circuit, among other courts. Note for disambiguation: a UK barrister also named Charles Phipps practices at 4 New Square in London — a different individual.
