Eric C. Green

I'll research this attorney before drafting the summary.

Let me dig into the specific cases and PTAB activity.

Let me verify which side the firm represented in the district court cases, plus his background.

Eric C. Green — patent litigation practice summary

Mr. Green is a partner in Norton Rose Fulbright's Austin, Texas office whose practice centers on patent litigation, complex commercial litigation, appeals, ITC Section 337 proceedings, PTAB inter partes reviews, and patent portfolio analysis. His technical background is in electrical/computer engineering and biomedical engineering, and his reported disciplines span mobile telecom and wireless communications, machine learning, video processing, data security and encryption, integrated circuit design and fabrication, power electronics, advanced networking, filtration media, oil and gas, and medical diagnostics — with stated experience on standard-essential patent and FRAND issues. (Sources: firm/IPWatchdog bio; Best Lawyers profile listing Litigation–IP and Litigation–Patent.)

The tracked docket data show four appearances, three on the defendant side and one on the plaintiff side, all through Norton Rose Fulbright US. The only litigation set in the data is the Harbor Island Dynamic, LLC / Quest Patent Research monetization campaign: the E.D. Tex. suits Harbor Island Dynamic, LLC v. NXP Semiconductors N.V. (No. 2:24-cv-00717) and the Samsung counterpart (No. 2:24-cv-00140), each of which was stayed pending the parallel PTAB proceedings. Caveat: the tracked entry for the Samsung matter is drawn from a service list and is marked unconfirmed, and the side labels in the source data are inconsistent with the underlying captions (Harbor Island is the plaintiff in the district court actions). In the PTAB filings I could verify, Mr. Green appears as counsel of record for Harbor Island Dynamic, the patent owner — i.e., the patent-holder side — not for Samsung or NXP. Given the small sample, the data do not support a strong plenary-side conclusion, though third-party ranking coverage of him emphasizes defendant-side work.

Notable tracked matters and outcomes. He is listed among counsel for Patent Owner Harbor Island Dynamic in the Samsung IPRs (IPR2024-01402/01403/01404/01405) and in the related NXP IPR (IPR2025-00954), alongside lead counsel from Fabricant LLP. Those proceedings resulted in PTAB final written decisions in February–March 2026 cancelling the claims of all four asserted patents ('886, '673, '609 and '826). Harbor Island appealed the '673 decision (Fed. Cir. No. 26-1670, dismissed by agreement on September 15, 2026), sought Director Review of the '609 and '826 decisions, and — after missing the 63-day deadline in IPR2024-01402 — obtained an extension of time to file its notice of appeal on an excusable-neglect showing, docketed as Fed. Cir. No. 26-1886. These outcomes are adverse to the client side he represented; I found no reported verdicts or wins attributable to him.

PTAB / IPR experience. Yes — his PTAB work is confirmed on the public record in the Harbor Island IPR family (2024–2026), including final-written-decision and Director Review stages, which is his most visible tracked activity. His firm bio also lists IPR proceedings as a core practice area.

Firm and credentials. All tracked appearances are with Norton Rose Fulbright US LLP, where he was promoted to partner in February 2022; I found no record of prior law firm affiliations, so his pre-2022 history is unverified. He is a registered patent practitioner (USPTO Reg. No. 59817). Best Lawyers lists a J.D. from The University of Texas (2009); no state bar admission was confirmed in the sources reviewed. Third-party USPTO-aggregation data (PatentBots) shows him of record on prosecution filings for large corporate and university applicants, but that data is self-described as potentially outdated and I would not rely on it without docket-level confirmation.
