About Us Mesmer & Delegate has offices in Manchester and Portsmouth, New Hampshire. While we serve people and businesses throughout New England, our law practice is actually nationwide and worldwide. Our focus here is unusually narrow for a smaller firm. For more than two decades (since 1986), our emphasis has been on business law, intellectual property (patents, trademarks, copyrights, trade secrets), estate planning, and commercial litigation. Narrowing our focus has improved our ability to solve problems in these law practice areas. Our Promise to You: We return calls usually the same day. We return all calls within 24 hours.
