Patent litigator Michael Amon helps large multinational companies across industries defend and prosecute intellectual property rights at trial and on appeal. He represents clients in district courts and appellate courts, post-grant proceedings, and TTAB opposition and cancellation hearings.

Michael’s practice encompasses all aspects of patent litigation, from discovery through trial, including motion practice, claim construction, expert witness selection and preparation, and overall trial strategy. He advises on ways to leverage IP portfolios and the tactical use of litigation to achieve business goals.

His experience runs the gamut, covering wide-ranging technologies with a focus on medical devices, chemical-related patents, pharmaceuticals, electrical engineering, computer science, and mechanical engineering-related innovations. He has favorably resolved cases involving everything from computer hardware and software to radio frequency identification (RFID) technology and from medical devices and chemical composition technology to golf balls and voting machines.

Because he has both asserted and defended IP-related claims, Michael brings an uncommon perspective in advising on and executing litigation strategies. Delivering convincing arguments grounded in the facts, he uses litigation tactically, making sure results will align with his client's goals.

Michael is most proud of his work for GlaxoSmithKline in which he and a Fish team successfully preserved GSK’s patent rights in a life-changing drug GSK spent years of research and more than a billion dollars to create and bring to market. 

Beyond the courtroom, Michael helps clients plan for the future. He evaluates the strength and weaknesses of their patents, vulnerability to infringement, possible redesigns of products to avoid infringement, and the benefits of strategic licensing, acquisitions, and sales of IP assets.

He enjoys the excitement of learning new things daily and working with incredibly brilliant people. Clients consider him bright, creative, engaging, and personable. They appreciate his ability to see the whole picture from all sides and his skill in helping them build, manage, and protect their innovations.

Michael is the vice office managing principal of Fish's Southern California office. He teaches a course on intellectual property law and patent litigation at the University of San Diego School of Law. Before joining Fish, Michael clerked for the Honorable James F. Stiven (2002-2003) and the Honorable Rudi M. Brewster (2003-2004) of the U.S District Court for the Southern District of California.

A first-generation American born to South American parents, Michael spoke Spanish before English. He keeps his culture alive speaking Spanish at home to his children and actively engaging in Hispanic organizations.
