William Raich, Ph.D., represents innovative companies developing biologics, pharmaceuticals, medical devices, and diagnostics. As a patent lawyer with a doctorate in cellular and molecular biology, he focuses his practice on patent litigation, pre-litigation counseling, and contentious proceedings at the U.S. Patent and Trademark Office (USPTO), applying his technical expertise and courtroom insight to develop simple, persuasive positions for clients.

Bill has substantial experience with traditional patent litigation in district court and arbitrations, as well as litigating under the Biologics Price Competition and Innovation Act (BPCIA) and litigating Abbreviated New Drug Application (ANDA) cases. He also represents clients before the Patent Trial and Appeal Board (PTAB) of the USPTO, appearing as lead counsel in numerous proceedings. In addition to his contentious work, Bill performs client counseling and opinion work, primarily in areas related to biologics, pharmaceuticals, and DNA sequencing. He has been recognized by LMG Life Sciences as General Patent Litigator of the Year in the DC area, as an Intellectual Property: Life Sciences Star, and honored for his contributions in the field of "General Patent Litigation." Bill was also named as a DC IP Star by Managing Intellectual Property and a Leading Patent Litigator in the DC area by Intellectual Asset Management. Benchmark Litigation also recognized Bill as a litigation star.

Bill served at the U.S. Court of Appeals for the Federal Circuit as a law clerk for the Honorable Randall R. Rader and the Honorable Jimmie V. Reyna. He has represented pro bono, including as lead counsel, multiple disabled veterans before the U.S. Court of Appeals for Veterans Claims.

Prior to joining Finnegan, Bill conducted post-doctoral research in molecular biology and neuroscience in the laboratory of Nobel Laureate Eric Kandel at Columbia University. He frequently speaks at conferences on issues such as the developing body of law relating to biologics.
