Summary: D. Brian King — patent litigation
Practice profile from tracked appearances. The tracked record is thin: two patent matters, both on the defense side. The technology spread is narrow but spans two distinct areas — (1) NAND/flash-memory and storage-management patents, via Longitude Licensing Ltd. et al. v. Apple Inc. (N.D. Cal. No. 3:14-cv-04275, filed Sept. 2014), in which Longitude asserted thirteen SanDisk-origin patents covering partial-block programming, data correction/scrub, wear leveling, power management and flash wake-up; and (2) Hatch-Waxman small-molecule pharma, via Veloxis Pharmaceuticals, Inc. v. Glenmark Pharmaceuticals Inc., USA (D. Del. No. 1:25-cv-00458, filed Apr. 2025, Judge Noreika), an ANDA case over extended-release tacrolimus (Envarsus XR) implicating U.S. Patents 8,685,998; 9,549,918; 10,166,190; 10,864,199; 11,110,081; 11,123,331; 11,419,823; and 12,083,103. Nothing in the tracked record shows Wi-Fi/standards-essential-patent work, software platform litigation, or mechanical arts.
Side preference. Entirely defense-side: 0 plaintiff appearances against 2 defendant appearances. Both clients are operating companies (Apple; Glenmark, a generics manufacturer) rather than NPEs/PAEs — the profile is defense of products and ANDA filers, not monetization-side assertion. The Longitude matter in particular places him on the receiving end of an NPE-style portfolio assertion, and the public docket in that case reflects a successful early defense result — Apple's motion to dismiss Longitude's willful-infringement allegations was granted with leave to amend in March 2015 — plus an extensive parallel IPR campaign (fifteen Apple IPR petitions filed September 2015 against the Longitude/SanDisk flash patents).
Firm context. Tracked firms are Clifford Chance US (role: counsel, on the Longitude/Apple matter) and DLA Piper (US) (role: Lead Counsel, on Veloxis/Glenmark). DLA Piper is separately documented as counsel of record for Apple in the Longitude IPR proceedings, which is consistent with the tracked entry. No in-house affiliation appears in the record.
Verification caveats — read before relying on this. I was unable to confirm a public practice profile matching this name in patent litigation. Searches for "D. Brian King" return a prominent international arbitration practitioner of that exact name (Freshfields Bruckhaus Deringer 1999–2018, now an independent arbitrator in New York/London; NYU Law J.D. 1990; Princeton B.A. 1985; law clerk to Judge Leonard B. Sand, S.D.N.Y., and Judge Harry T. Edwards, D.C. Circuit) whose firm history does not overlap with Clifford Chance or DLA Piper. I also could not locate "D. Brian King" on the public dockets for the two tracked cases — the Veloxis/Glenmark docket lists different counsel of record, and the Longitude/Apple docket lists different Apple counsel. Bar admissions, education, and PTAB/IPR appearances for the patent litigator in question are therefore not reliably sourced and are omitted here rather than guessed. If this profile matters for a filing or conflicts check, the two tracked docket sheets should be pulled directly from PACER to confirm identity, role, and any pro hac vice or PTAB registrations. Note also a related follow-on in the same drug dispute: Veloxis v. Glenmark (D. Del. No. 1:26-cv-00305, filed Mar. 2026, on U.S. Patent 12,403,095), which was dismissed without prejudice by stipulation on Aug. 27, 2026.
