Strategically located with multiple offices in New England, Sheehan Phinney focuses on solid IP procurement, enforcement, and strategy, while also considering related corporate law issues, thereby adding comprehensive business strategists to your team. Having headquarters in New Hampshire enables us to provide award-winning talent, but at below market cost.

Sheehan Phinney attorneys provide goal driven, practical, and cost-efficient advice to clients in matters concerning all aspects of IP, including patents, trademarks, copyrights, trade secrets, e-commerce, prosecution, litigation, licensing, legal opinions, IP portfolio management and consolidation, and Internet law. We do this by working with clients to evaluate, protect, and enforce their IP rights, and to ensure that those rights are part of an ongoing, overall business strategy, from start-up to exit.

We enjoy a varied client base ranging from solo inventors and start-ups, to Fortune 500 companies and major research universities. Regardless of the client size, our goals, quality of work, and dedication remain the same. Additionally, due to a large international client base and managing global intellectual property portfolios, we maintain long-term relationships with agents throughout the world, thereby obtaining strong discounts that we pass on to our clients. We are the exclusive New Hampshire law firm for Lex Mundi, enabling us to partner with counsel on a global level enhancing our ability to address clients' needs around the world.
