Lance Yang

I'll research this attorney's background before drafting.

Good foundation. Let me verify the firm bio and the specific tracked cases.

Lance Yang — patent litigation practice summary

Focus areas. Yang is a Quinn Emanuel trial lawyer whose IP practice centers on electronics and hardware/software technologies: semiconductors and chip-to-chip/memory interfaces, RF and wireless communications, consumer devices, networking and device-management software, satellite systems, and lithium-ion battery materials. His firm bio also lists copyright and general complex IP work, and he has litigated in district courts, the ITC, and before the PTAB, plus advising on patent licensing. His technical background (M.S. from Stanford in RF chip design and wireless communications; five years as an engineer at Maxim Integrated Products; registered with the USPTO) is consistent with that hardware/software tilt. Nothing in the tracked matters indicates pharma, life sciences, or mechanical-arts work.

Side preference — both sides, but not an NPE practice. The tracked list is nearly even (4 plaintiff / 3 defendant), and the pattern is operating-company-versus-operating-company rather than PAE work. On defense he represents large technology defendants — Samsung, Google, and Palo Alto Networks — against competitor and non-practicing-entity assertions; on plaintiff side he represents technology companies enforcing their own patents (ViaSat, STMicroelectronics, and China-based battery maker Ningde Amperex/ATL). He is listed as lead or likely lead counsel in several of the plaintiff matters.

Firm context. Yang has spent his litigation career at Quinn Emanuel Urquhart & Sullivan, where he is a partner; the firm lists him in its Los Angeles, San Francisco, and Seattle offices. No prior law-firm history surfaced in searches — his pre-legal career was in industry as an engineer at Maxim. All seven tracked appearances are Quinn Emanuel matters. Docket filings appear under both "Lance L. Yang" and "Lance Lin Yang" (Cal. Bar No. 260705), referring to the same attorney.

Notable matters. The best-documented outcome is Ningde Amperex Technology (ATL) v. Zhuhai CosMX Battery (E.D. Tex., No. 2:22-cv-00232), where Quinn Emanuel won a February 2024 jury verdict of willful infringement of three ATL lithium-ion battery patents (electrolyte, electrodes, separator), a $3.7 million running royalty, and a rare 27% enhanced-damages award in April 2024 — reportedly the first such enhancement for a Chinese plaintiff in that venue; the Federal Circuit cross-appeals (Nos. 2025-1037, 2025-1091) were dismissed by agreement in June 2026. He is on the Samsung defense team in the Headwater Research NPE campaign (E.D. Tex.), where Samsung secured summary-judgment/R&R rulings of invalidity on the '733 patent and the case was terminated in 2025, and the parallel UPC Düsseldorf action saw Headwater's EP 3 110 069 revoked (July 2025). His Quinn Emanuel bio also credits the team's $283 million jury verdict for ViaSat against Space Systems/Loral, the complete ITC defense win for Broadcom, NVIDIA, STMicroelectronics and others in Rambus's 337-TA-753 action, and Apple/Samsung and HTC ITC matters. He also appeared for Google in Rockstar Consortium v. Google and is tracked as defense counsel in Fortinet v. Palo Alto Networks. CNBC reported in September 2026 that a jury returned a $5.7 billion verdict for Taction Technology against Apple in a haptics patent case, quoting Yang as Taction's lead counsel; that result is reported, not independently confirmed in the sources reviewed here.

PTAB / IPR. He appears in PTAB proceedings — for example, listed as counsel of record in the CosMX/ATL battery IPR filings (IPR2025-00389 and related) — but the public record reviewed shows his strongest footprint in district court and ITC litigation rather than as a first-chair IPR specialist.

Bar / education. Admitted in California (2008) and to the USPTO; J.D., University of Pennsylvania Law School (2008); LL.M., Tsinghua University; M.S., Stanford University.
