Elissa Knoff’s practice includes patent prosecution and client counseling across a broad range of technological areas. She leverages her thorough understanding of patent law and her perspective on a patent’s lifecycle from procurement through enforcement in advising BoMc’s clients.

Before joining BoMc, Elissa was a patent litigation associate at a multinational general practice law firm. There, she represented clients through various stages of litigation. She developed both legal and factual theories, including by working with expert consultants and by thoroughly vetting prosecution histories. Through her prior practice, Elissa developed insight into the rigors that litigation places on patents and the importance of developing strong patent portfolios which can be effectively asserted.

Prior to entering practice, Elissa served as a law clerk to the Honorable Timothy B. Dyk at the U.S. Court of Appeals for the Federal Circuit. While in law school, Elissa served as an extern for the Honorable Joan H. Lefkow at the U.S. District Court for the Northern District of Illinois. She also served as Executive Articles Editor for the Northwestern Journal of Technology and Intellectual Property.
