Attorney Profile

William G. Cosmas devotes most of his practice to sophisticated civil litigation. He founded Cosmas Law LLC, based in Beverly, Massachusetts, in October 2020, and he represents clients across the greater Boston metropolitan region.

A great deal of Mr. Cosmas’s caseload is made up of business and commercial litigation. He has represented plaintiffs, defendants, and non-party witnesses in claims involving breach of contract, fraud, misrepresentation, construction disputes, employment law, trade secret misappropriation, business torts, intellectual property, antitrust, securities law, False Claims Act allegations, and generic pharmaceutical products covered by the Hatch-Waxman Act.

Mr. Cosmas has handled a variety of other matters as well. He has successfully represented clients in real estate litigation involving land use, trespass, and adverse possession and has successfully defended clients in state and federal white-collar criminal investigations. His successful track record in all of his professional endeavors has earned him a great deal of favorable recognition from his fellow members of the bar.

Mr. Cosmas attended Georgetown University, where he was active in student affairs and majored in philosophy before receiving a Bachelor of Arts in 2001. After he graduated, he worked as an account executive at a global public relations firm before enrolling at Boston College Law School. While he was there, Mr. Cosmas participated in moot court competitions and interned at the Middlesex County District Attorney’s Office before being awarded his Juris Doctor in 2007. Before opening his own practice, Mr. Cosmas was a partner at a well-known Boston law firm, and he is admitted to practice in Massachusetts and before both the U.S. District Court for the District of Massachusetts and the U.S. Court of Appeals for the First Circuit.

  • Do statutes of limitation apply with equal force to arbitration proceedings? Not necessarily. The Massachusetts Arbitration Act, G.L.c. 251, §1, et seq., “expresses a strong public policy favoring arbitration as an expeditious alternative to litigation for settling commercial disputes.” Miller v. Cotter, 448 Mass. 671, 676 (2007). The MAA, however, makes no reference to statutes of limitation as bars to the commencement of an arbitration., Co-Author, In arbitration, applicability of statutes of limitation unpredictable, Massachusetts Lawyers Weekly, 2017
  • Two years ago in this journal, I examined the process of obtaining a pardon in the Commonwealth of Massachusetts from the perspective of having represented one of the first successful petitioners for such relief since 2002. This article examines the Executive Clemency Guidelines issued by Governor Charles D. Baker (the “Baker Guidelines”) as compared to those that his predecessor, Governor Deval L. Patrick, issued in January 2014 (the “Patrick Guidelines”)., Author, A Clear View of a Narrower Path: Examining the Baker Pardon Guidelines, Boston Bar Journal, 2017
  • In the last weeks of his term, Governor Deval Patrick granted the first four pardons in the Commonwealth of Massachusetts since 2002.  Following public hearings on each petition, the Governor's Council approved all four, one of whom was my client. Obtaining clemency is a rare occurrence – combining legal and political processes with little guidance.  The journey from petition to pardon involves uncertainty for petitioners and their attorneys alike.  This article aims to shed some light on the process., Author, From Here to Clemency: Navigating the Massachusetts Pardon Process, Boston Bar Journal, 2015
