Jon Singer, a renowned life sciences industry leader and decorated trial attorney, is a senior principal in Fish & Richardson's life sciences litigation practice.
Jon founded Fish’s acclaimed Life Sciences Litigation Group in 2001, which has since grown to become one of the most respected practices in the country. Known as a meticulous tactician and a compelling oral advocate, Jon introduces impeccable planning and strategy into every case he manages.
Throughout his 30-year career, Jon has headed some of the firm’s most complex pharmaceutical matters. In many of these matters, he successfully reversed negative verdicts on appeal, earning him a reputation for turning challenging circumstances into wins for his clients. For example, in Prometheus Laboratories v. Mayo Collaborative Services, Jon and the Fish team took a pharmaceutical patent dispute all the way to the U.S. Supreme Court, achieving a reversal of a Federal Circuit Court of Appeals decision in what was recognized as the most important patent decision of the year. In Gilead Sciences, Inc. v. Merck & Co., Jon was trial counsel for Gilead in a case that initially resulted in a $200 million jury verdict against his client. He thenled the bench trial that resulted in the district court setting aside the jury verdict due to unclean hands.
Today, Jon mainly serves as a trusted advisor for the next generation of litigators in Fish’s Life Sciences Group, while still doing courtroom work for select clients. He frequently assists up-and-coming principals with trial preparation, strategic planning, witness preparation, and other practices to ensure they have the help and support they need to succeed in the complex and challenging practice of life sciences patent litigation. Jon also puts his experience to work as an expert witness in drug-related trials, applying his extensive knowledge of pharmaceuticals to patent and antitrust cases across the country.
Jon’s record of success has earned him substantial recognition throughout his career. He is a three-time Law360 “Life Sciences MVP,” a Daily Journal “California Lawyer of the Year,” and a National Law Journal “Winning Litigator,” among other awards.
In his free time, Jon enjoys writing fiction and completing cryptic crosswords.
