Ellyar Barazesh

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

Let me verify specific case outcomes and any additional background.

Let me check a couple more tracked cases for verifiable outcomes.

Ellyar Y. Barazesh — patent litigation practice summary

Focus. Barazesh's practice centers on post-grant practice before the USPTO — inter partes review and other PTAB proceedings, plus an active ex parte reexamination docket — with supporting district-court litigation, prosecution, and counseling work (Baker Botts bio). His technical background is electrical engineering: he holds a B.E.E. from the University of Minnesota (2012) and worked as a USPTO patent examiner on video compression and imaging before law practice. Reported technology coverage is broad rather than niche — computer hardware and software, memory, control systems, networking and Wi-Fi/messaging technologies, video and image processing, semiconductors, encryption, GUIs, location tracking, medical devices, footwear and sports equipment, and autonomous vehicles/UAVs. The tracked matters are consistent with that profile: automotive control/measurement systems (Longhorn Automotive), Wi-Fi and messaging patents (Malikie Innovations), and networking/software patents (Torchlight, Damaka, CardWare).

Side preference. All seven tracked appearances are plaintiff/petitioner-side (7–0), but the label is misleading: every one is a Unified Patents proceeding, in which Unified is a defensive aggregator challenging patents asserted by NPEs/PAEs, not an entity asserting its own portfolio. He is therefore best described as a petitioner-side post-grant challenger of NPE patents rather than a plaintiff's-side patent enforcer. His firm bio notes he has represented both petitioners and patent owners in IPR, and a 2023 Baker Botts power of attorney in DJI Europe B.V. v. Textron Innovations (IPR2023-01227) shows him on the patent-owner side — worth confirming whether that representation continued.

Firm context. Barazesh is currently a Senior Associate in Baker Botts LLP's Intellectual Property group, resident in Austin, Texas (USPTO Reg. No. 74,096). Before joining Baker Botts in 2023 — PTAB filings in Unified v. Torchlight show him withdrawing in July 2023 upon "chang[ing] employment" — he was Senior Patent Counsel at Unified Patents, LLC (from roughly October 2020), where he prepared and litigated post-grant proceedings. Earlier in his career he practiced at WilmerHale and Stoel Rives, focused on post-grant and district-court matters, and was a student associate/patent agent at Finnegan, Henderson, Farabow, Garrett & Dunner.

Notable matters, PTAB experience, and credentials. His PTAB docket is substantial: he was first back-up counsel in Unified Patents v. MemoryWeb (IPR2021-01413) and argued at the oral hearing as a LEAP practitioner; he handled the Unified v. Torchlight Technologies IPR of U.S. Patent 11,208,029 (instituted May 2023, terminated by settlement in September 2023); and he has appeared for petitioner in the onsemi/Greenthread IPRs (IPR2023-01242/-01243/-01244), Silicon Motion IPRs (IPR2024-01236/-01240/-01241, terminated by settlement in 2025), and Cirrus Logic and Semiconductor Components Industries matters. On the reexamination side, the CRU granted Unified's requests in two matters he handled — Longhorn Automotive's U.S. Patent 7,987,002 (April 2025) and Malikie Innovations' U.S. Patent 7,315,747 (July 2025) — while a Law360 item indicates the USPTO rejected at least one Unified reexamination request against a Malikie/BlackBerry-origin video coding patent (Unified's post in that September 2026 cryptography reexamination lists different counsel). Bar admissions: Texas, District of Columbia, and the USPTO. J.D., Georgetown University Law Center (2017), where he received the Leon Robbin Patent Award.

Note: Several tracked docket entries carry generic role labels ("Attorney," "Counsel") and one case is untitled; individual outcomes for the Competitive Access Systems, CardWare, and Damaka matters could not be independently verified and are not characterized above.
