Tammy Su

Tammy Su — Patent Litigation Practice Summary

Specialty / focus areas. Tammy Su is an IP litigator at Kobre & Kim focused on high-stakes disputes in the life sciences, pharmaceutical, and high-tech industries, including patent, trademark, copyright, and trade-secret litigation. Her tracked docket skews toward software/AI and electronics — AI-based voice/accent processing (Sanas v. Krisp), autonomous-vehicle control systems (Granite v. Tesla), and antenna/communications technology (Fractus v. ResMed) — consistent with her B.S. in biochemistry and her practice description covering both life sciences and tech.

Side preference. Su's tracked appearances are plaintiff-side in 6 of 8 matters, largely representing patent owners and NPEs (Granite Vehicle Ventures, Fractus, and two untitled matters), but she also defends operating companies: she represents Sanas.AI against Krisp Technologies and in Unified Patents' PTAB challenge. She thus works both sides, with a plaintiff/patent-owner tilt. All tracked appearances are at Kobre & Kim; before joining, she was an associate (later managing associate) at Orrick, Herrington & Sutcliffe's Silicon Valley office, in its IP group.

Notable cases and PTAB/IPR experience. Most prominent is Sanas.AI v. Krisp Technologies (N.D. Cal.), where Su is counsel to Sanas in a patent-infringement, trade-secret, and co-inventorship fight over real-time accent-conversion and voice-enhancement patents; in February 2026 the court denied Krisp's § 101 motion, letting Sanas' claims proceed. She also appears in Granite Vehicle Ventures v. Tesla (E.D. Tex., Judge Gilstrap), asserting self-driving fault-remediation patents — Tesla's IPR2025-00943 was denied institution — and in Fractus, S.A. v. ResMed and the related ResMed Corp. v. Fractus action. Her PTAB exposure is real but developing: she represents patent owner Sanas in Unified Patents v. Sanas AI Inc., and the Sanas/Krisp dispute has spawned parallel IPRs (IPR2026-00273/-274) in which her firm defends Sanas' patents. No verdicts or settlements specifically attributable to Su were verified.

Bar / education. Admitted in California (N.D. Cal.); J.D. cum laude from UC College of the Law, San Francisco (UC Hastings), B.S. in biochemistry from UC San Diego. Her firm profile does not list USPTO registration, and her background is otherwise lightly documented publicly, so some details above rest on the tracked case list and firm materials.
