I'll research this attorney before drafting.

Let me verify the tracked case and his current firm/bio.

T. William "Bill" Kennedy, Jr. — patent litigation practice

Focus. Kennedy is a patent litigator whose docket is concentrated in electronics and display-adjacent technologies rather than pharma or mechanical arts. His most heavily documented work is the Innovative Display Technologies / Delaware Display Group campaign over LED backlight and "light emitting panel assembly" patents (the '563, '547, '660, '816 and related family), asserted against automotive and consumer-electronics makers. He has also handled physiological-monitoring and wearable sensor patents (Valencell), flash-storage and interface technology (Super Interconnect Technologies, asserting UFS / MIPI M-PHY patents), device-to-device output and printing (Flexiworld), semiconductor/memory litigation involving source-code review (Palisade Technologies v. Micron), and telecommunications/networking patents (Redwood Technologies). His firm bio lists a B.S. in electrical engineering, which aligns with this hardware-and-standards-heavy mix.

Side preference. He works predominantly for patent owners — i.e., NPE/PAE-side plaintiffs — in district court. In the two tracked appearances he is listed on the defendant side of Mercedes-Benz USA LLC v. Innovative Display Technologies LLC; that caption tracks the PTAB proceedings in which Mercedes-Benz was petitioner and Kennedy's client IDT was the patent owner, so the "defendant" designation reflects the caption rather than a shift to defending operating companies. Elsewhere he is consistently counsel of record for asserting patent owners, including Valencell, Flexiworld, Super Interconnect, Palisade and Redwood. Within his trial teams he has generally served as back-up counsel alongside a registered-practitioner lead, not as lead.

Firm context. He is currently with Nelson Bumgardner Conroy P.C. (Dallas office, 2727 N. Harwood St.), having moved there in 2021 from Bragalone Conroy P.C., the firm listed in the tracked data. His earlier career began at Akin Gump Strauss Hauer & Feld after law school. Both Bragalone Conroy and Nelson Bumgardner Conroy are Dallas/Fort Worth IP boutiques with heavy patent-owner practices, and several former Bragalone Conroy colleagues (Justin Kimble, Jonathan Rastegar, Patrick Conroy) appear with him on the same matters, indicating a largely continuous team and client base across the move.

Notable matters and PTAB work. In the IDT/delaware Display campaign he was counsel of record for the plaintiffs in the consolidated E.D. Tex. litigation against automakers (Mercedes-Benz, Hyundai/Kia, Toyota, Honda, BMW, VW) and in D. Del. suits against Lenovo, LG and VIZIO; the May 2015 E.D. Tex. claim construction ruling went against his side on one term, holding claim 1 of the '816 patent indefinite. In Super Interconnect Technologies v. Sony (D. Del. 2019), the court denied Sony's Rule 12(b)(6) motion with Kennedy listed among plaintiff's counsel; related SIT actions against ZTE and Google were dismissed by joint motion. His PTAB footprint is substantial and sustained: pro hac vice appearances as patent-owner back-up counsel in roughly twenty IPRs, including IPR2014-01096/-01097/-01362, IPR2015-00487/-00506/-01666/-01717/-01866/-01867/-01868, the Valencell series IPR2017-00315/-00317/-00318/-00319/-00321 (Apple and Fitbit), IPR2021-00713/-00714 and IPR2022-00775 (Flexiworld, against Roku and Unified Patents), and IPR2025-01560 (Palisade v. Micron, where he filed a patent-owner declaration supporting discretionary denial). He appears in IPR proceedings by pro hac vice motion rather than as a USPTO-registered practitioner; no USPTO registration number appears in the sources reviewed.

Bar and education. State Bar of Texas No. 24055771 (licensed 2006); J.D., University of Texas School of Law (2006); B.S., Electrical Engineering, Texas A&M University (2003); admitted to the U.S. Court of Appeals for the Federal Circuit and the N.D., E.D. and W.D. of Texas. His PTAB declarations state he has never been suspended, disbarred or sanctioned.

Notes on the record: the two tracked entries are identical in caption and role, consistent with two docket entries for the same Mercedes-Benz/IDT PTAB matter rather than two distinct cases. Separately, a "Mr. Kennedy" appearing as a damages expert in Stratasys v. Shenzhen Tuozhu is a different individual and is not reflected above.
