Paul T. Parker

Specialty & side. Paul T. Parker is a Seattle-based intellectual property partner whose core practice is patent prosecution, portfolio strategy, and IP counseling for medical device and semiconductor clients (thrombectomy/neurovascular devices, cardiac and neurostimulation technologies, LED/semiconductor fabrication and process patents). Both tracked appearances are plaintiff-side on behalf of operating companies — Inari Medical (a med-tech company) and Microsoft — with no NPE/PAE defense work in the record, consistent with his profile as a prosecution/counseling lawyer who supports litigation rather than leading trial teams.

Firm context. Parker is a partner at Perkins Coie LLP (Seattle/Palo Alto) and firmwide chair of its Medical Device Industry Group; he is ranked by Chambers USA and IAM Patent 1000. Earlier in his career he was an associate at Seed & Berry (Seattle, 1995–1999) and Fredrikson & Byron (Minneapolis, 1993–1995).

Notable matters. In Inari Medical, Inc. v. Imperative Care, Inc. (N.D. Cal. 5:24-cv-03117), Perkins Coie represents Inari in a multi-patent thrombectomy infringement suit; Parker served as backup counsel for patent owner Inari in the related Imperative Care v. Inari Medical IPRs (IPR2025-01021/-01025/-01264) and handled prosecution of the asserted patents. The court denied Inari's preliminary injunction motion in September 2025. He also appears as counsel for Microsoft in IPRs challenging InterDigital Patent Holdings' wireless patents (e.g., IPR2024-00305, IPR2024-00538), which led to a pending Federal Circuit appeal (Microsoft Corp. v. InterDigital Patent Holdings, No. 25-2049, filed Aug. 2025).

PTAB/IPR & credentials. Although his practice is prosecution-centric, Parker has active PTAB experience on both sides — patent-owner backup counsel in the Inari IPRs and petitioner-side counsel in the Microsoft-InterDigital IPRs. He holds a J.D. from University of Minnesota Law School (1993, magna cum laude, Order of the Coif), a B.S. in mechanical engineering from Washington State University, and is admitted in Washington and before the USPTO.
