Stefani E. Shanberg

Specialty / focus areas. Stefani Shanberg is a patent litigator whose practice is concentrated in U.S. district court and International Trade Commission (Section 337) cases for technology companies. Her tracked docket spans video/streaming technology (Nokia's video-coding patent complaints against Amazon), software patents (Flexiworld v. Amazon), and cybersecurity-related patent claims (K. Mizra v. CrowdStrike). Firm and Chambers USA profiles describe her as representing technology companies in IP cases before federal courts and the ITC, with particular depth in Section 337 investigations — she is a past president of the ITC Trial Lawyers Association and the only West Coast-based lawyer to have held that role.

Side preference. Shanberg's practice is almost exclusively defense-side: all three tracked appearances are for defendants (Amazon twice, CrowdStrike once), and Perkins Coie's announcements highlight wins for operating companies such as Amazon and Spotify before the ITC and in federal court. No tracked NPE/PAE plaintiff work.

Firm context & notable matters. Shanberg is currently a partner in Perkins Coie's San Francisco office, which she rejoined in December 2022 after roughly 15 years at Wilson Sonsini Goodrich & Rosati (partner since 2007); her earlier tenure at Perkins Coie preceded that. She served as lead counsel for Amazon in the Nokia v. Amazon ITC investigations (e.g., Inv. No. 337-TA-1380) over video-coding patents; those matters settled in 2025 after ITC trials. She was trial counsel for Amazon in Flexiworld Technologies v. Amazon and lead counsel for CrowdStrike in K. Mizra LLC v. CrowdStrike; I could not verify outcomes in those two cases. Chambers USA ranks her for International Trade: Intellectual Property (Section 337) and California Patent Litigation.

PTAB/IPR & credentials. Her public profile emphasizes district court and ITC work rather than PTAB practice; the Amazon–Nokia dispute involved parallel IPRs, but PTAB filings identify other Perkins Coie attorneys as counsel, and I found no reliable evidence that she appears regularly in IPR/PGR proceedings. J.D., University of Texas School of Law (1998); admitted to the California bar (2000).
