David Seastrunk

I'll research this attorney's professional background before drafting.

Let me dig into notable cases and outcomes.

David C. Seastrunk — Senior Patent Counsel, Unified Patents, LLC

Focus and side of practice. Seastrunk's tracked docket is almost entirely petitioner-side work at the PTAB: 28 of 30 appearances are plaintiff/petitioner matters, and essentially all are post-grant challenges filed by Unified Patents (a defensive aggregator that files IPRs against patents asserted against its members, rather than a monetizing NPE). His two defendant-side appearances are the exception. This is worth framing carefully for the reader: the "plaintiff" label reflects Unified's role as IPR petitioner challenging others' patents, not patent enforcement on its own behalf. The counterparty patents he has challenged span consumer electronics and video/streaming (VideoLabs/VL Collective, Sonos), audio and smart speakers, mobile payments (RFCyber), VoIP (Damaka), touch sensing (Power2B), displays (Samsung Display), medical devices (Treace Medical, Moskowitz Family), pharmaceuticals (Actelion), mechanical consumer products (Monahan/UPPAbaby), and software/data platforms (AutoConnect, Data Health Partners). That breadth tracks the technical background described in his firm bio — electrical and mechanical arts including software, wireless communications, consumer electronics, industrial manufacturing, fibers/textiles/polymers, and medical devices.

Firm context. Seastrunk has been Senior Patent Counsel at Unified Patents since October 2019, when Unified announced his hire along with two other patent attorneys. Before that he spent several years at Finnegan, Henderson, Farabow, Garrett & Dunner, where he worked on all phases of post-grant proceedings, district court litigation, and ITC Section 337 investigations, plus patent prosecution and freedom-to-operate opinions. He is in-house at Unified, not at an outside firm.

Notable matters. He argued for Unified as appellee before the Federal Circuit in Engle Grange, LLC v. Unified Patents, LLC, No. 22-1524 (argued Apr. 3, 2023; Rule 36 summary affirmance, mandate May 2023). He was Unified's in-house counsel in Unified Patents, LLC v. Arsus, LLC, IPR2020-00948, where the Board entered adverse judgment after Arsus disclaimed all challenged claims and the Federal Circuit summarily affirmed in November 2021; he also appeared at the oral hearing in Unified Patents, LLC v. Varatec, LLC, IPR2019-01276. Other tracked proceedings include Torchlight Technologies (IPR2022-01500), Sonos, Samsung Display, Power2B, RFCyber, Damaka, and Tempus AI, and he is listed as lead counsel in Unified Patents, LLC v. FireNet Technologies, LLC. Note that in the VideoLabs/VL Collective '794 patent appeal decided by the Federal Circuit in February 2026, Unified's in-house counsel of record were Jessica Marks and Roshan Mansinghani, so that particular appellate win should not be attributed to Seastrunk even though he appears on other VideoLabs-related Unified matters. I found no published damages verdicts or district court trial results attributable to him; his public track record is concentrated in PTAB and Federal Circuit appeals, with reported outcomes skewing to Unified.

PTAB/IPR experience. This is the core of his practice — he appears regularly as lead or back-up counsel in IPR proceedings, and Unified's announcement describes his role as preparing and litigating post-grant proceedings before the Board.

Bar and education. J.D., University of North Carolina School of Law (2015); B.S., Textile Engineering, North Carolina State University, summa cum laude (2009); admitted in the District of Columbia, Virginia, and before the USPTO (Reg. No. 73,723). Caveat: the education, admission, and technical-background details beyond the Unified announcement come largely from firm-bio aggregator pages mirroring his Finnegan profile; I could not independently verify all of them against a current primary source.
