Robert D. Cohan

Robert D. Cohan is a founding partner at Cohan Plaut Rajsich LLP, where his practice primarily centers on complex business disputes and general business litigation. While the firm explicitly states it is not a patent law firm, Cohan has experience in business trade secret and intellectual property misuse cases, including patent infringement matters. His firm, organized in 1985, often handles business disputes on a contingent fee basis.

Based on tracked appearances, Cohan has exclusively represented plaintiffs in patent litigation. The most prominent example is Uniloc USA, Inc. et al. v. Microsoft Corporation, where he represented the plaintiff, a patent assertion entity, in a case involving software product activation patents. Although a jury initially awarded Uniloc $388 million, the district court later overturned this verdict. The Federal Circuit subsequently reinstated the infringement finding but remanded for a new trial on damages, leading to a confidential settlement between the parties in March 2012. The firm's "News" section also reports having recovered over $17 million arising from a patent infringement case, though specific details about this matter are not publicly linked to Cohan.

Cohan's professional background does not indicate a regular focus on Patent Trial and Appeal Board (PTAB) or inter partes review (IPR) proceedings. He was admitted to the Massachusetts Bar in 1974 and earned his law degree from The George Washington University Law School. He is admitted to practice before the U.S. District Court for the District of Massachusetts, the First Circuit Court of Appeals, and the U.S. Supreme Court.
