Brent N. Bumgardner

I'll research Brent N. Bumgardner's professional background to supplement the case data provided.

Let me verify the tracked cases and PTAB/IPR activity in more detail.

Let me verify the Roku IPR outcome and any Federal Circuit or settlement results.

Specialty / Focus Areas. Brent N. Bumgardner is a founding partner and principal at Nelson Bumgardner Conroy P.C. (Fort Worth, TX), where he concentrates on patent infringement litigation, patent licensing, and related commercial disputes (firm bio, nelbum.com). His tracked matters center on wireless-communications and consumer-electronics patents — Flexiworld's portfolio directed to IEEE 802.11/Wi-Fi and Bluetooth wireless display, streaming, and "casting" of digital content from mobile devices to TVs — and his broader docket shows extensive software/electronics work (e.g., cellular/LTE assertions by Cellular Communications Equipment LLC against Apple, Dell, and HTC; geo-location and streaming-media cases) alongside earlier medical-device matters. He holds a B.S. in chemical engineering but has litigated primarily in the software and wireless space.

Side / Role. All three tracked appearances are defense-side: Bumgardner served as lead counsel for patent owner Flexiworld Technologies in PTAB challenges brought by Roku and Unified Patents (IPR2022-00775; Roku proceedings on the '114, '031, and '233 patents). In parallel, however, his web-searchable docket reflects a practice on both sides — substantial plaintiff-side work for patent-assertion entities in the Eastern and Western Districts of Texas (e.g., Flexiworld v. Roku before Judge Albright, R2 Solutions v. Expedia, Unification Technologies v. Phison, and a 2026 Malikie Innovations v. Toyota appearance), as well as defendant representations. The tracked figures understate his plaintiff-side volume.

Firm Context. He is a founding partner of Nelson Bumgardner Conroy P.C., the Fort Worth-based successor (via Nelson Bumgardner Albritton P.C. and earlier firm iterations) of a boutique known for high-volume Texas patent litigation. Prior firms include a partnership at Monts & Ware, LLP and stints at McKool Smith, Munsch Hardt Kopf & Harr, and Strasburger & Price (firm bio; Martindale-Hubbell/Lawyers.com profiles).

Notable Matters & PTAB/IPR Experience. His most prominent tracked result is Unified Patents v. Flexiworld (IPR2022-00775), where the PTAB's November 2023 final written decision found no challenged claims of U.S. Patent 9,836,257 unpatentable — a full win for the patent owner (Patexia; PTAB record). He also prevailed in Roku v. Flexiworld (PGR2021-00111), where the Board denied institution. The underlying Flexiworld–Roku district-court litigation in W.D. Tex. settled in 2022, and the separate Flexiworld–Epson suit also settled. He appears regularly before the PTAB as patent-owner lead counsel (also designated in IPR2025-01182), consistent with his firm's listed IPR/CBM practice. He is admitted in Texas (1996), registered with the USPTO (No. 48,476), and admitted to the Federal Circuit, with a J.D. (1995) and B.S. chemical engineering (1992) from the University of Texas at Austin.
