We are pleased to announce that the firm has been ranked in the 2025 edition of Chambers USA. For the third year in a row, the prestigious legal guide recognized Sunstein as being among the top firms in Massachusetts for Intellectual Property Law. Additionally, Managing Partner Kerry L. Timbers, and Litigation Chair Lisa M. Tittemore earned recognition among the state’s top IP practitioners.

Chambers and Partners identifies and ranks leading firms and practitioners for its annual guides based on firsthand, in-depth research and interviews with in-house counsel and third-party experts. The 2025 researchers shared that Sunstein “attorneys are not only experts in their legal fields, but they are trustworthy, excellent communicators and possess strong business and technical understanding."

One firm client remarked during the research process that Sunstein is “an experienced team that provides services across a range of needs,” and another shared “they are strategic and forward-thinking and have exceptional analytical skills.”
