Charles B. Baker

I'll research this attorney before writing the summary.

Let me verify the tracked case and IPR experience.

Let me confirm the firm merger and counsel appearance in the tracked case.

Charles S. Baker — Troutman Pepper Locke LLP (legacy Locke Lord), Houston/Austin

*Note on name: the tracked case list identifies this attorney as "Charles B. Baker" of Locke Lord; the Locke Lord/Troutman Pepper Locke IP litigation partner who appears in this matter is Charles **S. *Baker. The middle initial appears to be a data-entry variant, but the identification is not certain from public docket sources and should be confirmed before relying on it.

Focus areas. Baker is a first-chair IP trial lawyer whose patent work spans consumer electronics/wearables, medical devices, oilfield services and drilling technology, computer hardware, software, networking, VoIP and data storage. Firm and Chambers profiles describe particular depth in the energy/oilfield services sector — downhole tools, perforating guns, PDC drill bits, closed-loop mud drilling and dual-activity offshore drilling — alongside repeated work in the Eastern and Western Districts of Texas. The tracked matter, Omni MedSci, Inc. v. Samsung Electronics Co. Ltd. et al. (E.D. Tex.), fits the electronics/medical-device pattern: it concerns wearable physiological measurement and pulse-oximetry patents asserted against Samsung, Fossil, Oura and OnePlus, and has generated parallel IPR/PGR challenges at the PTAB.

Side preference. The tracked data shows one defendant-side appearance and no plaintiff-side appearances, which is consistent with his broader public record as primarily a defense-side litigator for operating companies — large technology, energy and medical-device manufacturers facing NPE/competitor suits. He is not a plaintiffs'-bar or PAE monetization lawyer. That said, his representative-matters listings do include affirmative patent and trade-secret enforcement for oilfield services clients, so the practice is not exclusively defensive.

Firm context and notable matters. Baker joined Locke Lord in 2014 from Norton Rose Fulbright to lead the firm's Houston IP litigation group, and became co-chair of the firm's IP Litigation Practice Group. Since the January 1, 2025 merger of Locke Lord and Troutman Pepper, he practices at Troutman Pepper Locke, where he remains a co-chair of IP litigation. He is consistently ranked in IAM Patent 1000 and Managing IP's IP Stars (Patent — National/Texas), and Chambers USA (Intellectual Property — Texas, Band 4). Reported results include a January 2023 Houston jury verdict of non-infringement for a downhole-tools manufacturer facing two asserted patents and $30M+ in claimed damages (following a summary judgment of non-infringement on one patent), and a § 101 win in the Eastern District of Texas for a medical-device manufacturer that had been one of 30+ defendants to settle rather than litigate eligibility. He also has a significant copyright/trade-secret practice, including representation of the lead defendant in MGM v. Grokster.

PTAB / IPR experience. Chambers notes he regularly acts for companies in IPR proceedings, and his representative matters include defense of dual-activity offshore drilling patent suits that resolved after IPRs were instituted, plus a software/patent matter that settled following a Markman ruling. Public sources describe this as recurring PTAB work rather than a high-volume petition-filing practice; I could not verify from the available sources whether he personally signed the Samsung-side petitions in the Omni MedSci IPR/PGR family.

Bar / education. Admitted in Texas (1985); J.D. with honors, South Texas College of Law Houston (1985); B.B.A. in Accounting with honors, University of Texas at Austin (1982).
