Korula T. ("Sunny") Cherian — Patent Litigation Practice Summary

Specialty / focus areas. Cherian is a founding partner of an IP litigation boutique whose practice centers on complex patent and trade-secret disputes. His technical background is electrical engineering (MSEE), and he handles integrated circuit/semiconductor, computer hardware and software, networking and telecommunications, and mechanical-device matters (Benchmark Litigation; Cherian LLP bio). His most concentrated recent work is network/proxy technology for Bright Data Ltd. (residential-proxy patents, including the '319, '510, '342 and '344 patents litigated and appealed through 2025), with additional matters in digital imaging and semiconductor manufacturing. Firm materials also list life-sciences/biotech licensing disputes and ITC Section 337 work.

Side preference. His portfolio is mixed but currently tilts plaintiff/enforcement-side. Of the seven tracked matters, five are plaintiff-side and two defendant-side. That split reflects two distinct eras: earlier defense work for operating companies (representing Brocade/Foundry Networks against Chrimar, Lucent, Alcatel and Network-1; Hyundai in semiconductor cases), and a more recent plaintiff-side practice prosecuting and enforcing Bright Data's patent portfolio in the Eastern District of Texas and on appeal at the Federal Circuit. He also acts as patent owner in PTAB proceedings, which the tracking data records as the "defendant" role.

Firm context. He is the founder of the firm now known as Cherian Harkins Dunham LLP (CHD Law), headquartered in Washington, D.C. with offices in Oakland/Berkeley, California and Texas. The firm was founded in 2015 as RuyakCherian LLP, rebranded as Cherian LLP, and became Cherian Harkins Dunham on January 1, 2026, adding Robert M. Harkins, Jr. and Thomas M. Dunham as named partners (CHD Law announcement). His tracked appearances span all three firm names.

Notable cases and outcomes. The most prominent tracked matters are the Bright Data litigations and appeals. In Bright Data Ltd. v. Teso LT, UAB et al. (Oxylabs), an E.D. Tex. jury on November 5, 2021 found willful infringement and awarded $7,474,876 in lost profits; the case was stayed pending PTAB review, and the Federal Circuit subsequently affirmed the PTAB's invalidity findings (Fed. Cir., Nos. 23-2144 et al., Aug. 1, 2025), denied rehearing en banc (Oct. 1, 2025), and the Supreme Court denied certiorari (2026) — an adverse final outcome for the client on the asserted claims. He was also on the team that won the Federal Circuit affirmance in Bright Data Ltd. v. BI Science (2009) Ltd. (Fed. Cir. 2023), which incorporated a settlement and arbitration award requiring BI Science to exit the proxy-services business worldwide. Other reported results: summary judgment of invalidity affirmed for Brocade/Foundry in Chrimar Systems v. Foundry Networks, a favorable settlement in Allflex USA v. Avid, and a 2025 win for Optimum Imaging Technology in six patent suits. Tracked appeals 23-2145, 23-2442 and 23-2443 are the consolidated Bright Data v. Code200 Federal Circuit matters.

PTAB / IPR experience. Yes — he appears regularly in post-grant proceedings and the firm markets using the same core team across district court, PTAB and appeals. Tracked proceedings include IPR2021-01492 and IPR2022-00915 (Bright Data, patent owner), and he has appeared in IPR2017-00640/00642 (Brocade/Ruckus, petitioner) and the Bright Data v. Oxylabs IPRs (IPR2023-00185/186/187, petitioner).

Bar / education. Member of the California State Bar (No. 133967); admitted to the Federal Circuit, Ninth Circuit, the U.S. Supreme Court, and multiple federal district courts, including E.D. Tex. Education: J.D., University of California, Davis; MSEE, George Washington University; BSEE, University of Mysore.
