Saina Shamilov — Patent Litigation Practice Summary

Saina Shamilov is a partner at Fenwick & West LLP, where she co-leads the firm's patent litigation group and has practiced since joining as a litigation associate in the early 2000s. Her patent work concentrates on computer and internet technologies: AI, cloud computing, machine learning, natural language processing, networking and telecommunications, e-commerce/web services, gaming, and CRM/database systems. She also handles non-tech subject matter — most visibly the beauty-technology/e-commerce company Lashify — and litigates in the Northern District of California, District of Delaware, E.D. Virginia, and the Eastern and Western Districts of Texas, as well as before the ITC and the Federal Circuit. Her technical background as a former software engineer is a recurring theme in coverage of her practice.

Side preference. The tracked docket and public record show a defense-heavy, operating-company practice: 0 plaintiff-side and 3 defendant-side tracked appearances, nearly all on behalf of Amazon entities. She has been ranked by Patexia among the most active patent attorneys representing defendants. The one notable complainant-side matter is Lashify, where she served as co-lead counsel in a Section 337 ITC investigation and related district court litigation — so her experience is not purely defensive, but the dominant pattern is defending large technology companies against NPE/PAE and competitor suits.

Notable matters. Her most prominent tracked cases are the Amazon defense matters. In PersonalWeb Technologies (N.D. Cal. MDL), she helped obtain summary judgment of non-infringement for Amazon and 80+ AWS customers; the Federal Circuit affirmed in a precedential opinion she and the firm describe as enlarging Kessler preclusion for patent defendants, followed by a reported $4.8M fee award to Amazon. She obtained a full defense verdict for Amazon in Freshub (W.D. Tex.), where the plaintiff sought $246M over Alexa-powered devices, and a full defense verdict in Virginia Innovation Sciences (E.D. Tex.), plus a § 101 win in E.D. Va. affirmed by the Federal Circuit. She also secured a trial win for Amazon/eero against TrackThings (mesh networking) and, for Lashify, a $30.5M jury verdict plus a 2025 Federal Circuit ruling on the ITC domestic-industry requirement that Law360 highlighted among the year's top patent decisions. In the tracked Amazon.com v. WAG Acquisition matter, she was on the Amazon team that prevailed in the related IPRs; the Federal Circuit affirmed the Board's obviousness findings in March 2026. In the tracked Athena Security, LLP v. Amazon.com case (W.D. Tex., filed Feb. 2026), she appeared as lead counsel for the Amazon defendants. Results above from the Federal Circuit and district courts are documented; the verdict and fee figures are largely as reported by Fenwick's own case summaries and trade press.

IPR/PTAB experience. Yes — she appears regularly in PTAB proceedings as backup or lead counsel on Amazon IPR petitions (e.g., petitions involving WAG Acquisition, Datonics, and VB Assets patents), and has argued PTAB-related issues through the Federal Circuit.

Bar / education. Admitted in California (2001) and registered to practice before the USPTO (Reg. No. 48,266); J.D., Santa Clara University School of Law (2001), and a B.S. in computer science (1997). Note: sources differ on the UC campus for her undergraduate degree (Martindale lists "University of California"; a 2015 Silicon Valley Business Journal profile says UC-Davis), so that detail should be confirmed before publication.
