Jiang Wu — Patent Litigation Practice Summary
Focus areas. Mr. Wu's tracked litigation work clusters in semiconductor and consumer-electronics technologies: the Harbor Island Dynamic matters involve semiconductor-on-insulator (SOI) switching circuits and related semiconductor fabrication patents, while the DivX matters concern video compression and streaming codec technology. His prosecution-side profile (USPTO Reg. No. 79165) is broader, spanning consumer electronics, computer software, LCD/LED displays, MRAM/STT-RAM memory, image sensors and digital cameras, Li-ion batteries and smart grid, medical devices, and semiconductor devices and processes — a range consistent with a general electrical/electronics practice rather than a single narrow technical niche. A published K&L Gates biography also describes U.S. International Trade Commission Section 337 experience on behalf of an LCD manufacturer and a semiconductor company.
Side preference. The record is overwhelmingly defense-side: six of seven tracked appearances are on the defendant side, with only one plaintiff-side entry (the Samsung declaratory/appellate matter against Harbor Island Dynamic). He has represented operating companies — Samsung, NXP, and Realtek — against patent-assertion plaintiffs (Harbor Island Dynamic, a licensing/NPE-style entity, and DivX, a video-technology licensor), and he appears in both district court and PTAB proceedings for those clients.
Firm context. He is currently listed at Norton Rose Fulbright US LLP in Chicago, where the USPTO register and PTAB filings place him alongside NRF's Texas-based IP litigators (Eagle Robinson, Richard Zembek). Before that he was at K&L Gates in Chicago, where he worked on the DivX appeals and ITC matters. His earlier professional background, per his K&L Gates biography, was as in-house IP counsel in Sony Corporation's intellectual property division.
Notable cases and outcomes. The most prominent tracked matters are the Harbor Island Dynamic dispute — Harbor Island Dynamic, LLC v. NXP Semiconductors N.V., No. 2:24-cv-00717 (E.D. Tex., Judge Gilstrap; later stayed) — and the parallel IPRs, including NXP Semiconductors N.V. v. Harbor Island Dynamic, LLC, IPR2025-00954 (U.S. Patent 7,745,886; instituted September 2025, with oral argument set for January 2026) and the related Samsung/NXP IPRs (IPR2024-01402 et seq.), in which he is named as counsel in PTAB filings. On the K&L Gates side he was appellate/ITC counsel for the defendants in DivX, LLC v. Samsung Electronics Co. and DivX, LLC v. Realtek Semiconductor Corp. (the DivX PTAB/Federal Circuit line of cases includes Netflix, Inc. v. DivX LLC, 84 F.4th 1371 (Fed. Cir. 2023)). He does not appear to be lead trial counsel in a reported district court verdict; his verified role is PTAB and appellate briefing and ITC work.
PTAB/IPR experience. Yes — he is named as counsel in multiple inter partes review proceedings arising from the Harbor Island Dynamic / Samsung / NXP semiconductor litigation, indicating a recurring PTAB practice.
Bar and education. Ph.D. (2011) and M.S. (2008), Tokyo Institute of Technology (Electronics and Applied Physics / Innovative and Engineered Materials); registered before the U.S. Patent and Trademark Office (Reg. No. 79165); languages Japanese and Mandarin.
Caveats. Sources are inconsistent on his credential status: his K&L Gates biography identifies him as a "Patent Agent" admitted only to the USPTO, while the tracked roles (counsel of record, appellate counsel) ordinarily imply state-bar admission as an attorney. The two may reflect different points in time, or the tracked roles may not distinguish between attorney and registered-patent-practitioner status. I could not independently verify a state bar admission or confirm that the K&L Gates and Norton Rose Fulbright entries are the same individual, and geographic and technical overlap suggests they are, but that identification is not conclusively sourced. Any attorney-profile write-up should confirm credential status directly with him before publication.
