Gilbert Greene

I'll start by verifying the attorney's professional background, since the tracked case list contains only a single untitled entry. Note that "Gilbert Greene" is a relatively common name, so I'll be careful about disambiguation.

I've identified the likely match: Gilbert A. "Bert" Greene, a registered patent attorney (Reg. No. 48,366) in Austin, Texas. Let me verify his recent cases, firm history, and PTAB work.

Let me verify the specific case outcomes and PTAB participation more precisely.

Note on identification and data limits. The tracked case list contains a single entry with no case name, so the case-list counts are only one data point and cannot by themselves establish a practice pattern. The attorney is best matched to Gilbert A. "Bert" Greene (USPTO Reg. No. 48,366), a registered patent attorney in Austin, Texas — a name shared by other, unrelated lawyers (e.g., Gary A. Greene of Caesar Rivise in Philadelphia, a distinct practitioner), so the profile below is drawn from the Duane Morris and Texas/PTAB records for Gilbert A. Greene specifically.

Focus areas. Greene's practice centers on patent litigation, with additional depth in copyright, trademark and trade secret litigation, and in patent prosecution, opinions and portfolio management in the chemical engineering, chemistry and mechanical fields — consistent with his B.S. in chemical engineering. Firm-published technology descriptions span wired and wireless networking, Power over Ethernet, wireless telecommunications, e-commerce systems, geographic information systems, middleware, video security, computer graphics, computer hardware, biofuel production, chemical and petrochemical processing, and DNA analysis. His recent docket work skews toward Wi-Fi/IEEE 802.11 standard-essential patents and connected-device/IoT technology, including smart home and security hardware.

Side preference. The tracked data show one appearance, on the defendant side as lead counsel, and nothing on the plaintiff side. Firm and docket reporting indicate a mixed practice historically — Duane Morris states he "has represented both patent holders and accused infringers" — but the recent and documented matters are heavily defense-side: he defends Vivint Smart Home (and its parent NRG Energy) against assertions by Malikie Innovations/Key Patent Innovations, and firm materials describe defenses for real estate software, payments software, semiconductor, cybersecurity, and oilfield-services clients. On the available record he reads as a defense-oriented litigator who has also represented patent owners, with the single tracked entry too thin a sample to call a firm-side preference.

Firm context, bar and education. Greene is a partner at Duane Morris LLP and managing partner of its Austin office; he joined in October 2017 from Norton Rose Fulbright US LLP (the firm formed from Fulbright & Jaworski) to open the Austin office, and earlier PTAB powers of attorney list him at Fulbright & Jaworski. He was admitted in Texas in 2004 and is admitted before the Federal Circuit, the U.S. Patent and Trademark Office, and several district courts including the Northern, Western and Eastern Districts of Texas and the Western District of Wisconsin. He holds a J.D. with honors from the University of Texas School of Law (2004; managing editor, Texas Intellectual Property Law Journal) and a B.S. in chemical engineering with highest honors from UT Austin (1998).

Notable matters and PTAB/IPR experience. Firm-listed results include a summary judgment of non-infringement on all asserted claims for an oilfield-services defendant in the Western District of Texas, a summary judgment of patent invalidity for a major technology client, and a bench-trial damages award plus permanent injunction for Trojan Battery in a trademark case. His most prominent current tracked matter is the Malikie Innovations / Key Patent Innovations v. Vivint Smart Home litigation in the Eastern District of Texas, part of a multi-defendant Wi-Fi/BlackBerry-portfolio campaign; the Vivint case (2:25-cv-00555) ended in a joint dismissal with prejudice in January 2026 with no adjudication of validity or infringement, and he filed the motion to dismiss on behalf of Vivint and NRG in the parallel ADT action. He has meaningful PTAB experience: as back-up counsel in covered-business-method and IPR proceedings at Fulbright/Norton Rose Fulbright for Ticketmaster, Hilton, Priceline/The Priceline Group, Urbanspoon and OpenTable/OLO, and more recently as petitioner's counsel for Vivint in IPR2026-00300 (U.S. Pat. 7,583,191) and in an IPR challenging Malikie's U.S. Pat. 11,119,756. He has been listed in The Best Lawyers in America since 2015 and in Texas Super Lawyers (2019–2020), per those directories; no published verdict or Federal Circuit opinion in his name surfaced in this search.
