Regis Calvin Worley, Jr.

I'll research this attorney before drafting the summary.

Let me verify the firm transition and the tracked cases.

Regis C. Worley, Jr. — patent litigation practice summary

Focus areas. Worley is a registered patent attorney and mechanical engineer (B.S., UC Santa Barbara; M.S., San Diego State) whose practice spans complex IP litigation, patent prosecution, trade secret disputes, IP diligence, and validity/non-infringement opinions. Firm bios describe his technology experience as sensors, medical devices, manufacturing equipment, software and computer hardware, and consumer electronics. His tracked cases, however, center on a single dispute family — optoelectronics and fiber-optic transceiver/photodetector module patents asserted between Applied Optoelectronics, Inc. and Cambridge Industries USA, Inc. in N.D. Cal. and before the PTAB. He also has patent interference experience at the USPTO. No pharma or life-sciences patent litigation appears in the tracked record.

Side preference. The tracked data is essentially even: three plaintiff-side and three defendant-side appearances. Notably, all six arise out of the same Applied Optoelectronics/Cambridge Industries conflict, where the mirrored captions reflect parallel district court and PTAB proceedings rather than a consistent client alignment — Cambridge is the petitioner in IPR while AOI is the patent owner, and the captions run both directions. The record therefore supports a conclusion that he works both sides of patent disputes rather than a plaintiff/NPE or defense-only posture. He appears in a defense-side fee motion in the AerSale matter in S.D. Fla. (submitting a supporting declaration), but that evidence is thin.

Firm context. All six tracked appearances list Eversheds Sutherland (US) LLP, where he was Counsel in the firm's San Diego office. Per a July 28, 2025 Cozen O'Connor announcement (covered by Law.com and Global Legal Post), he left Eversheds Sutherland and joined Cozen O'Connor as a member on July 31, 2025, part of a four-lawyer IP group (with Nicola Pisano, Scott Penner, and Jose Patiño) opening Cozen's North County San Diego office. The tracked case list appears to predate that move; his pre-Eversheds history is described only generally as IP/litigation associate roles at several global and regional firms.

Notable matters, outcomes, and PTAB experience. His most prominent tracked matter is the AOI–Cambridge Industries dispute. Cambridge filed five IPRs against AOI's patents in January 2025; the USPTO discretionarily denied institution as to the ’826 and ’116 patents based on "settled expectations" (patent age), and the Federal Circuit denied Cambridge's mandamus petition challenging that practice on December 9, 2025 (In re Cambridge Industries USA, No. 2026-101, nonprecedential). On July 27, 2026, a divided PTAB panel issued a final written decision finding Cambridge had not shown the challenged claims of the instituted IPR patent unpatentable — a win for AOI, with Cambridge reportedly planning an appeal. Worley appears in PTAB filings in this family (including IPR2025-00436 concerning the ’024 patent) and in USPTO correspondence under both Eversheds Sutherland and Cozen O'Connor, indicating regular IPR involvement.

Bar and education. Admitted in California (2004); U.S. Court of Appeals for the Federal Circuit; C.D. Cal. and S.D. Cal.; registered to practice before the USPTO. J.D., Thomas Jefferson School of Law (2004, summa cum laude; editor-in-chief, law review).

Caveat: the plaintiff/defendant counts and firm attributions above are taken from the authoritative tracked list; the Cozen O'Connor move is verified by firm and press sources, but I could not verify any trial verdicts, damages awards, or settlements personally attributable to him beyond the PTAB and Federal Circuit developments described.
