Saurabh Gupta Counsel

Washington, D.C.

Saurabh leverages interdisciplinary training in biology, materials science, and electronics to deliver laser-focused, trial-ready advocacy—simplifying complex technologies into persuasive arguments that both win in court and drive clients’ commercial goals. Clients seek him out for his deep experience, analytical rigor, and razor-sharp instincts in consequential patent disputes.

Saurabh has applied these skills across a spectrum of market-leading disputes. He was instrumental in securing a favorable settlement for a blockbuster lung cancer therapy on the eve of trial after years of litigation and in defending a top-selling osteoporosis drug against validity and infringement challenges. He helped obtain inventorship recognition in landmark proceedings involving the first-in-class COVID-19 mRNA-LNP vaccine that saved millions of lives and generated billions in revenue. He protected a small biotech innovator’s next-generation DNA sequencing platform with innovative design-arounds against aggressive patent assertions and reinforced a major electronics manufacturer’s defense in a multi-jurisdiction jury trial over internet-based digital content sales, with substantial damages at stake.

Saurabh was a founding staff editor of Georgetown Technology Journal. Saurabh’s PhD thesis—which proposed a CRISPR-based therapy for common infections—earned the Bill & Melinda Gates Foundation Global Health Award as one of the five most innovative solutions to a global health challenge.

Saurabh has represented clients before U.S. district courts, the Patent Trial and Appeal Board, the U.S. International Trade Commission, and the U.S. Court of Appeals for the Federal Circuit, and is registered to practice before the U.S. Patent and Trademark Office.
