Robert A. Delafield II

Attorney Summary — Robert A. "Bobby" Delafield II (Reg. No. 64,709)

Specialty / focus. Delafield's tracked docket centers on software and wireless content-streaming/transfer patents: all five tracked appearances arise from the Flexiworld v. Roku dispute and related PTAB proceedings over patents directed to wirelessly streaming digital content and pairing mobile devices with output devices. His current firm bio describes a practice focused on pharmaceutical patent litigation, with additional experience across software, medical devices, antitrust, licensing/settlement transactions, IP opinions, and patent/trademark prosecution — consistent with his chemistry background (B.S., Texas A&M; M.S., UT Arlington).

Side preference. He works predominantly on the patent-owner side. The 2-plaintiff / 3-defendant split is misleading in substance: both sides reflect the same core representation of patent-owner/licensing entity Flexiworld Technologies (an NPE associated with Quarterhill, f/k/a Wi-LAN) — enforcing its patents against Roku in W.D. Tex. and defending those same patents against Roku- and Unified Patents-initiated IPR/PGR challenges. He has also represented patent owner Unification Technologies against petitioners including Micron and Silicon Motion.

Firm context. His tracked appearances were as back-up counsel at Nelson Bumgardner Conroy (Fort Worth/Dallas; formerly Nelson Bumgardner Albritton) during 2020–2023. His current firm bio indicates he previously practiced at Wilson Sonsini Goodrich & Rosati and is now Counsel at Windels Marx Lane & Mittendorf (Florham Park, NJ). Note: a court docket shows a Windels Marx appearance terminated in Feb. 2024, but his firm bio appears current as of this writing.

Notable matters & PTAB/IPR experience. He is regularly involved in IPR/PGR proceedings. In the flagship Flexiworld Technologies, Inc. v. Roku, Inc. (No. 6:21-cv-00767-ADA, W.D. Tex.), the parties settled in 2022 and Roku's related IPRs (IPR2022-01112–01114, 01267–01269) were terminated pre-institution. In the parallel Unified Patents challenge to Flexiworld's wireless content-transfer patent, the PTAB upheld the challenged claims (Nov. 2023 decision) for the NBC team on which he served. In Unification Technologies matters he was designated lead counsel in at least one Micron IPR (IPR2021-00940).

Bar / education. J.D. with honors, University of Texas School of Law (2008); admitted to the USPTO, Federal Circuit, and E.D. and W.D. of Texas per his firm bio. (Identification note: the Nelson Bumgardner and Windels Marx records reflect the same "Bobby" Delafield, confirmed by shared USPTO reg. no. and nickname in PTAB filings.)
