Event Details 

Blake focuses his practice on patent litigation and counseling for clients in the biotechnology and pharmaceutical industries.

A registered patent attorney, Blake has deep subject-matter knowledge in the areas of biochemistry, molecular and cellular biology, gene synthesis, recombinant DNA technology, immunology, pharmaceuticals, therapeutic methods, diagnostic assays, and vaccines.

He counsels pharmaceutical companies in the areas of Paragraph IV design strategies, Hatch-Waxman litigation, and biosimilar market opportunities. Blake’s broader experience includes preparing patentability, infringement, and invalidity opinions; prosecuting U.S. and foreign patent applications; developing patent portfolios; advising on complex IP licensing and transactional due diligence; and counselling on trade secret protection, litigation avoidance, and risk management. Blake represents patent owners and challengers in inter partes reviews before the Patent Trial and Appeal Board.

Blake is not just a litigator; he’s a trial lawyer. His ability to bring clarity to complex issues through effective depositions and examinations of witnesses have led to significant victories for his clients. Blake’s notable trial wins in the pharmaceutical sector include a favorable decision of non-infringement in the first ever case to go to trial under the Biologics Price Competition and Innovation Act and the only successful defense to date of patents on a transdermal testosterone product. 

In addition to his patent practice, Blake represents clients in trademark and trade secret litigation. He has represented a major river cruise company in trademark and breach of contract litigation and a group of major league baseball teams in trade secret litigation over methods for pitching a baseball.

Blake graduated from DePaul University College of Law. He earned a master’s degree in molecular cell biology from Washington University in St. Louis and his bachelor’s degree in biology, cum laude, from Birmingham-Southern College.

Outside of his legal practice, Blake enjoys volunteering as a baseball coach. He takes great pride in mentoring kids and teaching them the right way to play sports, and has taken several of his baseball teams to play in tournaments up and down the East Coast.
