Gregory L. Hillyer

I'll research this attorney before drafting the summary.

Let me dig into the specific tracked case and his patent litigation / PTAB history.

Let me check his firm history and notable patent litigation results.

Gregory L. Hillyer — Patent Litigation Practice Summary

Focus areas. Hillyer's practice is a generalist IP litigation and prosecution practice rather than a single-technology specialty. Firm and firm-transition materials describe his litigation and prosecution experience as spanning pharmaceuticals, biotechnology, electronics, telecommunications, and business methods — consistent with his technical background (M.S. in organic chemistry, University of Pittsburgh). The one fully tracked patent case, Trinity Info Media, LLC v. Hornet Networks, Inc., involved software/communications patents (U.S. Patent No. 9,087,321 and related patents) asserted against a social-networking/messaging app operator. A substantial share of his docket is trademark and TTAB work rather than patents, so the patent-specific sample is thin.

Side preference. The tracked-appearance data is one-sided: 2 of 2 appearances plaintiff-side, both as lead counsel, both through Hillyer Legal. That reflects a recent pattern of representing patent-assertion plaintiffs (Trinity Info Media is a patent-holding entity). His longer docket history is more mixed, however — it includes defense-side work for operating companies, such as representing VMR Products in the Fontem Ventures v. NJOY e-cigarette patent litigation (S.D. Fla. 2014) and SIM2 U.S.A. in Allen Video Technology (S.D. Fla. 2015), alongside plaintiff-side matters (e.g., GPS Industries and Travel Photo). The tracked data should therefore be read as a recent snapshot, not a career-long plaintiff-only practice.

Firm context. Hillyer is the principal of Hillyer Legal, PLLC, a Washington, D.C. boutique (5335 Wisconsin Ave. NW). Before founding it, he was a partner at Brinks Gilson & Lione, joining in 2016 with five other attorneys from Feldman Gale, P.A., where he had been managing partner of that firm's Washington, D.C. office. He is not in-house.

Notable matters and PTAB/IPR. The most prominent tracked case is Trinity Info Media, LLC v. Hornet Networks, Inc. (C.D. Cal. No. 2:21-cv-01351), filed February 2021; Hillyer appeared pro hac vice for plaintiff, and the case was closed by joint stipulation to voluntarily dismiss in September 2021. No verdict or settlement terms are publicly verifiable. The second tracked appearance in the data is an unnamed plaintiff-side matter at Hillyer Legal with no docket detail available; I could not independently verify it. On PTAB experience, he has appeared as lead counsel in inter partes review (power of attorney filed in IPR2015-00859), and his firm marketing lists post-grant proceedings, IPR, PGR, and ex parte reexamination among his services; the public record does not show him as a high-volume IPR practitioner. He has presented CLE on claim construction's impact on litigation and PTAB proceedings (2017) and on patent insurance and litigation financing (UT Law Advanced Patent Law Institute, 2019).

Bar and education. J.D. with honors, Temple University Beasley School of Law (2000); B.S. chemistry, SUNY Oswego (1989); M.S. organic chemistry, University of Pittsburgh (1992). Admitted in Pennsylvania (2000), Florida (2003), Maryland (2007), and D.C. (2008); registered to practice before the USPTO (Reg. No. 44,154); admitted to the Federal Circuit and Fourth Circuit. He has taught as an adjunct professor at American University Washington College of Law.

Caveat: the professional-history details above come from firm press releases, martindale/Super Lawyers profiles, and USPTO/PTAB filings. The docket-derived case history is from third-party aggregators and may be incomplete.
