Eric Caligiuri — patent litigation summary
Focus areas. Caligiuri's practice centers on patent and trade secret litigation in federal district courts and before the ITC, with a technical emphasis on electronics and optics. His firm bio and case history describe work spanning semiconductor products and processes, networking, mobile device components and applications, and systems-on-a-chip, and his tracked matters are heavily concentrated in fiber-optic/optical transceiver technology (Applied Optoelectronics' pluggable transceiver module patents). Representative past matters include 3D printing (Envisiontec v. Formlabs), RF switch devices (Peregrine Semiconductor), set-top boxes and in-home networking (Entropic Communications, MoCA standard-essential patents), smartphones/smart TVs (Samsung ITC investigation), and IC chip manufacturing (Anza Technology v. Novatel Wireless). He also holds a mechanical engineering B.S. and a materials engineering M.Sc., and is a registered patent attorney who handles prosecution alongside litigation.
Side posture. The tracked record is genuinely mixed — two plaintiff-side and two defendant-side appearances — and the split should be read with care. His most visible current work is patent-owner/plaintiff side: he appears for Applied Optoelectronics as plaintiff in Applied Optoelectronics, Inc. v. Accelight Technologies, Inc. (N.D. Cal. No. 4:24-cv-09041-HSG) and in the related Eoptolink action (N.D. Cal. No. 5:24-cv-08165-NW), and for plaintiff GoTV Streaming in GOTV Streaming, LLC v. Netflix, Inc. (C.D. Cal.). The "defendant" labels in the tracked IPR entries (e.g., IPR2025-01567) reflect the patent-owner/respondent posture in PTAB proceedings where AOI is the patent owner, not a distinct defense practice. Earlier defense work includes representing Texas Instruments in Cradle IP, LLC v. Texas Instruments (D. Del.) and Samsung entities in an ITC investigation. Net: he does not fit a pure operating-company-defense or NPE-plaintiff profile; he works both sides, with his current docket weighted toward patent-owner enforcement.
Firm context. He has been at Weintraub Tobin since March 2015, joining the San Diego office as Of Counsel from Covington & Burling (following shareholder Jo Dale Carothers). His State Bar and USPTO records and December 2025 PTAB filings continue to list Weintraub Tobin, and he is consistently listed as Of Counsel. One caveat: the structured tracking data attributes the AOI v. Accelight district court appearance to DLA Piper as lead counsel, but every public filing I located in that case lists Caligiuri (SBN 260442) and Carothers under Weintraub Tobin as AOI's counsel, with Perkins Coie for Accelight; I could not verify any DLA Piper affiliation, and his bar record shows none. That attribution appears to be a data error, but I flag it rather than resolve it.
Notable matters and outcomes. GOTV Streaming, LLC v. Netflix, Inc. produced a December 2023 Central District of California jury verdict awarding GoTV $2.5 million in past damages on one wireless content-rendering patent, with Netflix prevailing on the second (his firm publicly discussed the verdict; I did not independently confirm his name on the face of the docket). In the AOI campaign, he helped defeat Accelight's motion to dismiss (order dated April 23, 2025) before the case was stayed pending IPR institution decisions. Earlier reported results include a summary judgment of non-infringement for Texas Instruments affirmed by the Federal Circuit in Cradle IP, a complete dismissal of a four-patent ITC investigation for Entropic Communications during fact discovery, and ITC findings for Samsung of no infringement and invalidity as to several asserted claims.
PTAB/IPR experience. Yes — he appears regularly, though in a supporting role. He is listed as back-up counsel under 37 C.F.R. § 42.8 mandatory notices for patent owner Applied Optoelectronics in multiple IPRs, including IPR2026-00122 and the Accelight-challenged proceedings around the '301, '116, '690, '367 and '818 patents; Jo Dale Carothers is lead counsel. His tracked IPR role is back-up counsel, not lead.
Bar and education. Admitted to the California bar in 2008 (SBN 260442) and registered with the USPTO (Reg. No. 58,121); J.D. cum laude, University of San Diego School of Law (2008, Order of the Coif), M.Sc. in materials engineering, CSU Northridge, and B.S. in mechanical engineering, UC San Diego. He has been recognized as a Southern California "Rising Star" in IP litigation (2015–2019) and is a contributing author to Weintraub Tobin's IP Law Blog and co-host of its "The Briefing" podcast.
