Established in 1918, WilmerHale's Boston office has grown from a five-lawyer office to a diverse practice of approximately 250 lawyers who serve an ever-expanding national and international client base. Our clients range from established industry leaders to emerging companies that reflect the New England region's status as one of the premier technology and life science centers in the country.

Our Boston office is a hub for the firm's litigation, corporate and intellectual property practices. Lawyers in our Corporate and Securities Litigation Practices are New England leaders in the defense of technology companies and their officers and directors in complex shareholder and consumer class actions. Many core members of our renowned Intellectual Property Litigation Practice are based in Boston, and have served as lead counsel in hundreds of major patent and trademark litigations. Chambers USA acknowledged our Boston Corporate Practice with a first-tier ranking, citing WilmerHale's outstanding track record with respect to a vast array of corporate matters. Chambers USA has also ranked our Boston Intellectual Property Practice in Band 1 in Massachusetts for the past 18 years (2003–2022). Clients said, "They have broad coverage and they are sharp lawyers; they provide a phenomenal service and achieve major successes; they manage their cases in a very organized fashion and are always communicating the progress of the issue at hand."

Clients of our Boston office benefit from our experience in other core areas such as bankruptcy and commercial, environmental, labor and employment, real estate, and tax. In addition to actively contributing to our strong tradition of pro bono representation, the Boston office is a major center for the firm’s Community Partnerships. This philanthropic outreach program encourages WilmerHale employees to contribute financial support, pro bono legal representation, volunteer service and in-kind donations in partnership with area nonprofits.
