Juanita R. Brooks

Based on the case data and public records, this is a professional summary of Juanita R. Brooks's patent litigation practice as of May 11, 2026.

Juanita R. Brooks is a principal at Fish & Richardson focusing on high-stakes patent trials and appeals. Her practice covers a wide range of complex technologies, including pharmaceuticals, medical devices, software, and electronics. She has represented major corporations in the life sciences and technology sectors, such as Gilead Sciences, Microsoft, Allergan, and Fresenius Medical Care.

The provided data indicates Ms. Brooks's experience on the defendant side of patent litigation, which is strongly supported by her public case history. She primarily defends operating companies against infringement allegations, often from non-practicing entities. A key example from the tracked cases is her role as lead counsel defending Symantec Corp. against patent infringement claims brought by Intellectual Ventures I LLC. In that matter, after a jury trial, the district court and the Federal Circuit ultimately found the asserted software patents invalid as ineligible under 35 U.S.C. § 101.

Ms. Brooks has secured numerous significant outcomes for her clients. For Gilead Sciences, she famously had a $200 million jury verdict overturned by proving litigation misconduct by the opposing party, a decision affirmed by the Federal Circuit. She also obtained a complete jury verdict of non-infringement for Microsoft in a case where the plaintiff sought over $60 million. While known for her defense work, she has also achieved substantial plaintiff-side results, including a $235 million jury award for GlaxoSmithKline in a pharmaceutical patent case. Her strategies have incorporated post-grant proceedings at the U.S. Patent and Trademark Office to invalidate asserted patents, as seen in her successful defense of Fresenius.

Ms. Brooks joined Fish & Richardson in 2000. She earned her law degree from Yale Law School in 1977 and is a member of the California bar.
