Amy Hayden focuses her practice on patent litigation and trade secret matters across a wide variety of industries, including pharmaceuticals, chemicals, hardware, and software. She has experience drafting various motions in both federal and state court, working with experts to draft reports and declarations, managing discovery, handling claim construction issues, and taking and defending depositions. As an on-site member of trial team in a patent infringement matter, she prepared both fact witnesses and technical experts for testimony, prepared graphics for trial to explain the technology at issue, and drafted various trial motions. Amy has also represented both petitioners and patent owners in inter partes review (IPR) proceedings before the USPTO. She additionally has an active Federal Circuit practice, with experience in briefing appeals from both district courts and the PTAB.

Amy also has first-hand trial experience through her pro bono practice. She recently led a trial team that represented a California state prisoner in an Eighth Amendment excessive force case. After a week-long trial in federal court in San Jose, the jury awarded both compensatory and punitive damages to the prisoner. Amy provided the opening statement, conducted the direct examination of the plaintiff, and the cross-examination of both the defense medical expert and two defendants. Amy has also represented numerous clients in family court to obtain restraining orders and custody and visitation orders. In one of those cases, she handled a two-day bench trial on her own, assisting her client in obtaining a restraining order.

While in law school, Amy was an Article Editor for the Berkeley Technology Law Journal and she served as a Judicial Extern to the Honorable A. Howard Matz for the United States District Court for the Central District of California. Amy has research experience in organic, medicinal, and polymer chemistry.
