Gareth Edward DeWalt — Patent Litigation Practice Summary

Focus areas. DeWalt is an IP litigator whose practice centers on complex patent and trade secret matters. His firm bio and representative matters describe experience in computer hardware and software, telecommunications, and pharmaceuticals, with specific case experience spanning set-top box hardware and software, WAN optimization, data compression and transmission protocols, small-molecule diabetes drugs, and 3G power-control technology. His Bunsow De Mory tracked matters add ridesharing/transportation-software patents (the Carma portfolio). We also note he has a technical background as a former software engineer, which is consistent with the hardware/software and telecom emphasis of his docket.

Side preference. The tracked docket for this attorney skews plaintiff/patent-owner (3 plaintiff-side vs. 1 defendant-side), and that reflects his current Bunsow De Mory work: he is on the Carma Technology team asserting ridesharing and delivery patents against Uber, and on the TOT Power Control team that won a $110.7 million jury verdict against Apple. His broader career record, however, is genuinely two-sided: much of his earlier practice was defense-side for operating companies (Comcast, Sun Microsystems, major investment banks), plus offensive work for Riverbed against a competitor. He is therefore best characterized as a both-sides litigator who currently spends more of his tracked time on the patent-owner/assertion side.

Firm and prior history. He is Of Counsel at Bunsow De Mory LLP (Redwood City, CA). Before that he practiced at Davis Polk & Wardwell and Skadden Arps, and before law school he worked as a software engineer/developer. He is not in-house.

Notable matters and outcomes. Publicly verifiable results include: TOT Power Control, S.L. v. Apple (D. Del.), where a jury found Apple's iPhones and iPads infringed a 3G power-control patent and awarded $110.7 million — DeWalt was a member of the Bunsow De Mory trial team; Rovi Corp. v. Comcast (Cal., N.Y., and ITC), where he guided the technical defense and the firm reports ITC findings of no violation, summary judgment/dismissal of several patents, and a Federal Circuit Rule 36 affirmance of patent invalidity; Sprint Communications Co. v. Comcast (D. Kan., D. Del., E.D. Pa.), including an infringement finding in the firm's offensive E.D. Pa. case and resolution of the Kansas action, in which Sprint sought close to $1 billion; Realtime Data, LLC v. Morgan Stanley, Goldman Sachs, J.P. Morgan Chase, et al. (S.D.N.Y.), summary judgment of noninfringement affirmed by the Federal Circuit; Versata Software, Inc. v. Sun Microsystems (E.D. Tex.), full defense finding of noninfringement and invalidity; and Riverbed Technology, Inc. v. Silver Peak Systems (D. Del.), a second-chaired trial that resolved by settlement. In the tracked Carma Technology Corp. v. Uber Technologies litigation (E.D. Tex., No. 2:25-cv-00029), he represents Carma on five asserted patents; Uber has since filed a set of parallel IPRs directed at each patent (IPR2026-00305 through -00309). He also represents Pfizer in a trade secret action against former employees and Regor Therapeutics concerning diabetes-drug technology (D. Conn.).

PTAB / IPR experience. His tracked appearances include one defendant-side matter captioned Unified Patents v. Carma Technology Ltd., which on its face is a PTAB-style challenge in which Carma appears as patent owner (i.e., the responding side); we could not independently verify the outcome or docket details of that proceeding from public sources. The Carma-side IPRs noted above are publicly visible, though lead PTAB counsel of record on those is listed as other Bunsow De Mory attorneys, and the PTAB filings reviewed identify Michael Flynn-O'Brien and Wayne Helge rather than DeWalt in the counsel block. We therefore cannot confirm that he is a regular IPR/PGR first-chair; his PTAB footprint appears to be secondary to his district court and ITC practice.

Bar and education. Admitted to the State Bar of California (No. 261479, admitted December 11, 2008); also admitted before the Federal Circuit, the N.D., C.D., and E.D. Cal., and the District of Colorado. Education is inconsistently reported: State Bar records list UCLA School of Law, while his firm bio lists a University of Michigan J.D. (Order of the Coif) and a B.S. in computer science from Michigan. Because the two sources conflict on the law school, that point should be treated as unverified.
