Chris Z. Liu

I'll research this attorney before drafting.

Let me verify additional details and check for prior firm history.

Let me check for Justia/court profiles and any news of his move to Fennemore.

Chris Z. Liu — patent litigation summary

Chris Z. Liu is a Director in the Intellectual Property practice group at Fennemore Law, where his work spans patent litigation, patent prosecution and counseling, IP transactions, IP enforcement for multinational companies, export control, and related regulatory matters. His stated technical focus is electronics- and engineering-heavy: semiconductors, 3G/4G/5G standards-essential patents, GPS/navigation, Wi-Fi routing, data encryption, MEMS, LEDs and control circuitry, tunable lasers and electro-optic materials, medical devices and imaging, clean energy, and nuclear fusion. Firm materials list past clients including Google, Cisco, Huawei, LG, Samsung, Xiaomi, and TSMC, and describe appearances in district courts (N.D. Cal., C.D. Cal., E.D. Va., W.D. Tex., E.D. Tex., S.D.N.Y., and D. Del.), the Federal Circuit, the PTAB, and the ITC.

Side preference. The available record indicates a defense-side practice. The tracked-appearance data shows 1 defendant-side appearance and 0 on the plaintiff side, and the firm's representative-matters list consists entirely of defending large operating companies (electronics, telecom equipment, e-cigarette, and Silicon Valley technology clients) rather than asserting patents for NPEs/PAEs. The single tracked case, however, is recorded without a case name or docket detail, so it cannot be independently verified or characterized beyond defendant-side.

Firm context. Fennemore is his current firm, where he holds the title of Director. His prior firm history is not publicly identified by name: Fennemore's bio states only that he previously advised U.S. and international clients from the Washington, D.C. and overseas offices of "leading international law firms." One caveat worth flagging — a 2023 conference speaker listing describes a Chris Liu as counsel in DLA Piper's Hong Kong office with a George Washington University J.D. and a University of Science and Technology of China physics background matching this attorney's profile; the match is suggestive but I could not confirm it is the same individual, so treat that prior affiliation as unverified.

Notable cases / outcomes. No case names, verdicts, appeal dispositions, or settlements attributable to him could be verified in public sources. All representative matters on his firm bio are anonymized (e.g., seven Federal Circuit appeals arising from PTAB decisions on 3G/4G/LTE technologies for a multinational telecom equipment company; fifteen W.D. Tex. information-technology suits and eleven N.D. Cal. navigation/map/email suits for a large technology company; an ITC Section 337 investigation on tobacco heating articles; and multi-patent campaigns involving Wi-Fi router technology, 4G LTE, GPS/maps, and security cameras). These are self-reported descriptions without case citations, so results should not be relied on without further checking.

PTAB / IPR. His practice includes regular PTAB work; the firm bio lists multiple IPR groups (three IPRs on e-cigarette technology, three on map/GPS technology, two on security camera technology, and two on solar cell manufacturing), plus Federal Circuit appeals from PTAB decisions.

Bar / education. Admitted in Massachusetts and the District of Columbia, the U.S. Court of Appeals for the Federal Circuit, and the USPTO; J.D., George Washington University Law School, with graduate work in physics/electrical engineering (Brandeis; UMass Amherst) and a B.S. in modern physics from the University of Science and Technology of China.
