Aaron L. Parker — Patent Litigation Practice Summary

Specialty / focus areas. Aaron Parker is a Washington, DC-based partner at Finnegan, Henderson, Farabow, Garrett & Dunner LLP, where he focuses on patent and trade secret litigation before U.S. district courts, global litigation counseling, prosecution, and post-grant proceedings (Finnegan profile; National Law Review). His deepest technology experience is in mechanical and medical device matters — coronary stents, dialysis systems, imaging, pacemakers, and catheters — plus sports/fitness/outdoor products, stormwater drainage, oil-and-gas equipment, and consumer electronics including wireless/mobile technology. His tracked appearance in Microsoft Corp. et al. v. InterDigital Patent Holdings Inc. (plaintiff side, Finnegan) is consistent with that broader wireless/electronics docket, though his firm profile emphasizes medical and mechanical work.

Side preference. The tracked data shows one plaintiff-side appearance and none for defendants, but the public record shows a genuinely mixed docket. Parker has represented plaintiffs (Abbott in the stent wars; StormTech/Advanced Drainage Systems in stormwater-chamber litigation) and defendants (Tetra Tech in Pavemetrics Systems v. Tetra Tech; patent owner Advanced Drainage Systems in IPR defense). He is best characterized as working both sides rather than specializing for NPEs or operating companies.

Firm context and notable matters. Parker has spent his career at Finnegan and was named partner there in 2015; he previously led the firm's mechanical practice group (UVa Magazine class notes; Finnegan profile). No prior-firm history was identified in public sources. His most prominent result is the Abbott stent litigation (Medtronic Vascular v. Abbott Vascular, N.D. Cal.), which settled on the eve of jury selection with Medtronic paying Abbott $400 million to resolve all global stent disputes (Finnegan profile). The tracked Microsoft v. InterDigital matter ran alongside Microsoft IPRs against InterDigital patents (IPR2024-00305/-00306/-00538); the parties' Federal Circuit appeal (No. 25-2049) was dismissed by agreement on November 6, 2025 (CAFC order).

PTAB/IPR experience. Parker appears regularly in PTAB proceedings on both sides: he defended patent owner Advanced Drainage Systems in IPR2017-00777/-00526 (institution denied; one decision designated "informative" on § 325(d)), served as lead counsel for petitioner Head Sport GmbH in IPR2024-01099, and has been designated lead/back-up counsel in other IPRs (e.g., IPR2015-01256). Bar/education: Admitted in Virginia and DC, before the USPTO (Reg. No. 50,785), Federal Circuit, and Court of Federal Claims; J.D. with honors, George Mason University School of Law (2003); B.S., University of Virginia (1999) (Finnegan profile; UVa Magazine).
