Brianna L. Silverstein

Brianna L. Silverstein — Patent Litigation Practice Summary

Silverstein is a Washington, D.C.–based patent litigator and counsel at Faegre Drinker Biddle & Reath LLP, where she handles the full lifecycle of patent cases — pre-filing investigation, claim construction, expert and damages work, trial, and appeal — across mechanical, electrical, and computer-science technologies. Her docket spans voice-search/digital-assistant software (Cortana/Bing), consumer electronics, vacuum-cleaner engineering, and consumer products (milkshake machines, footwear, radiation-treatment software), with additional trademark, copyright, and Copyright Royalty Board work. She joined Drinker Biddle & Reath and remained through the 2020 merger that formed Faegre Drinker; the firm promoted her to counsel in December 2021.

Her practice is consistently defendant-side, defending operating companies — she has no tracked plaintiff-side or NPE-prosecution appearances. In the tracked case, Parus Holdings, Inc. v. Microsoft Corporation (W.D. Tex., transferred to W.D. Wash.), she served as out-of-state counsel for Microsoft against NPE Parus's voice-browsing patents; Microsoft won transfer out of W.D. Tex. in December 2022, and the related IPR2022-00804 terminated as settled in March 2023. She was also part of the Faegre Drinker team that secured an ITC victory for Pioneer against Broadcom's six-patent complaint (2020), and has appeared for Microsoft and LG as appellees in Federal Circuit appeals in the Hafeman cases (Fed. Cir. 24-1600, among others).

She regularly appears before the PTAB in IPR proceedings — typically defending patent owners — including pro hac vice appearances and expert depositions for Dyson in SharkNinja v. Dyson (IPR2023-01322/-01324), and she co-founded Drinker Biddle's PTAB Trial Blog. Note that court and PTAB dockets list her as "Brianna Lynn Silverstein" or "Brianna L. Silverstein"; this matches the firm's "Brianna Forbes Silverstein" profile (same DC office, bar numbers, and email). She is barred in Virginia and D.C., is admitted to the Federal Circuit and several district courts, and earned her J.D. from George Washington University Law School (2009) and B.A. from the University of Maryland (2006), following a 2009–2010 DOJ Civil Division clerkship.
