Joseph L. Korbel — Patent Litigation Profile

Focus areas. Korbel's tracked patent work is limited to a single matter, so his patent docket does not yet show a technology specialty. That case, Cortex MCP, Inc. v. Visa, Inc., involves credential-verification and digital-identity patents (U.S. Patent Nos. 9,251,531, 9,954,854, 10,749,859, and 11,329,973, all titled "File Format and Platform for Storage and Verification of Credentials"), asserted against the Visa Token Service — i.e., payment tokenization, digital wallets, and NFC-based transaction verification. His firm-published practice areas are general commercial litigation, tort/insurance and personal-injury defense, employment, professional liability, and premises liability; intellectual property is not listed among them. His patent experience should therefore be read as that of a local-counsel/team member rather than a first-chair patent litigator.

Side preference. The tracked data show two plaintiff-side appearances and zero defendant-side — both entries arising from the same matter, where he served in one instance as local counsel and in another as counsel for plaintiff Cortex MCP. This is too thin a sample to establish a plaintiff/NPE-prosecution orientation; it reflects a single engagement, not a portfolio. Note that his broader practice at Davis, Cedillo & Mendoza is defense-oriented in the tort, insurance, and professional-liability space.

Firm context. Korbel is an associate at Davis, Cedillo & Mendoza, Inc., a San Antonio litigation boutique (State Bar No. 24127174). No prior firm history relevant to patent litigation is publicly sourced; he joined the firm after law school.

Notable case and procedural posture. In Cortex MCP, the case was filed in the Western District of Texas (No. 6:23-cv-00048) on January 26, 2023, and transferred to the Northern District of California (No. 5:23-cv-05720-EJD, Judge Edward J. Davila) on November 3, 2023, over plaintiff's opposition. Visa filed five IPR petitions (IPR2024-00486 through -00490) challenging all claims of the patents-in-suit in January 2024; the district court granted a stay in July 2024 and extended it thereafter. The PTAB issued four final written decisions in July 2025 with mixed but largely Visa-favorable results; Patent Owner's Director Review requests prompted Director John Squires to delegate review to a Delegated Rehearing Panel in October 2025, which declined to disturb the findings in November 2025. The decisions are on appeal at the Federal Circuit (No. 26-1259). Lead counsel for Cortex was Susman Godfrey; Korbel's role was as Texas local counsel alongside that team, so the substantive patent advocacy is not attributable to him.

PTAB / IPR experience. No source shows Korbel appearing in the IPR proceedings. Patent-owner side representation in the Cortex IPRs was handled by Armond Wilson LLP; the IPRs are relevant only as context for the district court case in which he appeared.

Bar and education. Admitted Missouri (2020), Kansas (2021), and Texas (2021); U.S. District Courts for the Western District of Missouri and District of Kansas, and the U.S. Court of Appeals for the Tenth Circuit (as listed in firm/Martindale profiles). J.D., University of Kansas School of Law, 2020; B.B.A., Baylor University, 2012.

Caveat: Korbel's patent litigation record rests on a single tracked case, and his firm biography does not identify IP as a practice area. Any assessment of a patent specialty would be speculative on the available sources.
