Gregory Booker is a patent trial attorney who thrives on a challenge. He excels in the most complex cases, representing clients in jury and bench trials in U.S. District Courts throughout the country, in appeals, and in post-grant proceedings before the Patent Trial and Appeal Board.

Greg has extensive experience in all phases of litigation, from pre-suit investigation, fact and expert discovery, and claim construction through motion practice, trials, and appeals. He is exceptionally skilled in handling the most complicated, game-changing patent cases for pharma, biotech, medical device, and material-based companies. He has prevailed in cases involving a variety of technologies, including pharmaceutical formulations, biologics, drug delivery systems, orthopedic devices, dental products, antivirals, cardiac medications, contact lenses, and polymers, among others.

Through careful fact analysis, intensive discovery, and witness and expert examination, he builds the strongest case possible and then develops and delivers clear and convincing arguments that often prove critical in securing a favorable ruling. In one noteworthy matter, Greg’s analysis was key in helping client Cehalon prevail in Hatch-Waxman litigation over its cancer pain medication Fentora®. Although the court did not find in Cephalon’s favor regarding its Orange Book-listed patents, Greg’s argument on a different patent won the day, setting the client up for success, keeping its brand on the market, and staving off infringers. In another matter, Greg was a member of the team that successfully defended Gilead Sciences against a $2 billion infringement allegation. Greg helped wipe out a $200 million jury verdict against Gilead while prevailing on an “unclean hands” defense against Merck.

Beyond the courtroom, Greg has helped clients strengthen their patent portfolios by correcting weaknesses, strengthening patent claims, and addressing vulnerabilities to infringement and invalidity claims.

Greg instructs newer lawyers through the firm’s in-house training program. The training includes courses on witness preparation, depositions, and trial presentation.

Before joining Fish & Richardson, Greg was a product development senior scientist with Johnson & Johnson Consumer Health, where he developed wound and skin care products.
