Keith A. Walter, Jr. — patent litigation practice summary

Focus areas. Walter's patent work spans software and cloud infrastructure, telecommunications/networking, automotive and consumer electronics, semiconductors, medical devices, and pharmaceuticals (including Hatch-Waxman). His four tracked appearances are all against Intellectual Ventures entities: Travelers Indemnity Co. v. Intellectual Ventures I LLC (D. Del. No. 1:26-cv-00397) and Munich Re America Services, Inc. v. Intellectual Ventures I LLC (D. Del. No. 1:26-cv-00417). Both are declaratory-judgment, non-infringement actions in which insurers/insureds responded to IV licensing demands over patents IV asserts against users of open-source infrastructure (Docker, Kubernetes, Spark) — i.e., software-stack technology rather than Wi-Fi standards or life sciences. His broader docket, per firm and third-party profiles, includes mesh networking (JSDQ Mesh Technologies v. Rio Tinto America), automotive diagnostic tools (Bosch Automotive Service Solutions v. Autel, Ford Motor Co. v. Autel), software copyright/trade secret matters (Niksun v. Intellic Networks), and ITC work (In re Certain Dental Ceramics).

Side preference. The tracked counts (4 plaintiff, 0 defendant) should be read carefully. He is not a PAE/NPE-side prosecutor; his plaintiff-side patent work consists of declaratory-judgment and commercial plaintiffs, most notably insurers and corporate defendants taking the offensive against an active NPE. Firm bios describe him as having represented both plaintiffs and defendants and as serving frequently as Delaware local counsel for national firms in District of Delaware IP disputes, which is a role he filled in the Travelers matter (Faegre Drinker) and, as Delaware co-counsel, in the Munich Re matter (Lewis Brisbois). One tracked entry is an unspecified lead-counsel engagement and cannot be characterized further.

Firm context. Walter is currently a partner in the Wilmington, Delaware office of Lewis Brisbois Bisgaard & Smith, joining in October 2025 in the Intellectual Property & Technology and Directors & Officers Litigation practices. He was previously a partner at Faegre Drinker Biddle & Reath (formerly Drinker Biddle & Reath) in Wilmington, and earlier an associate at the IP boutique Ratner & Prestia. Between roughly 2019 and 2025 he served as general counsel of a national direct-to-consumer health and wellness e-commerce company — he is not currently in-house.

Notable outcomes, PTAB, and credentials. The two IV matters are the most prominent tracked cases; both were filed in spring 2026 and, as of the available dockets, remained at the pleading/stipulation stage, so no merits outcomes are verifiable. Firm materials claim PTAB experience and list ITC and USPTO practice, but I found no publicly verifiable IPR/PGR proceeding numbers in which he is named counsel — treat "regular PTAB practice" as asserted but unsourced. Reported career results include a Hatch-Waxman temporary restraining order, a summary judgment of inequitable conduct in a semiconductor-equipment case, and a favorable resolution of a patent license dispute for Linzer Products after defeating a motion to dismiss. He is a registered patent attorney; B.S. in chemistry, Illinois State University (1993); J.D. cum laude, Temple University Beasley School of Law (1998); admitted in New York (1999), Delaware (2001), and Pennsylvania (2007).
