When litigation and other IP enforcement controversies arise, experienced trial lawyers at Hamilton Brook Smith Reynolds are ready to protect and advance the interests of clients, both as plaintiffs and as defendants.

Our firm has a proven record in litigation representing clients that range from Fortune 500 companies with hundreds of millions, if not billions, of dollars in dispute to individuals with modest amounts at stake but who can constitute “bet the company” disputes. In addition to representing clients in Massachusetts federal and state courts, our firm's litigators have been lead counsel in cases in New Hampshire, Maine, New York, New Jersey, Delaware, Texas, California, Illinois, and elsewhere around the country.

Our firm's philosophy in litigation and other disputed matters is that success means achieving the client's overall business goal. Sometimes that goal is best achieved by vigorously fought litigation. At other times, negotiation, mediation, or arbitration may be more advantageous. Therefore, we believe that close communication with the client is the key to developing a successful strategy adapted to the client's particular needs. The strategy also must be constantly reevaluated as the matter develops. Attention to costs is a critical component of our communications to ensure that the strategy fits the dispute's practical value as well as the client's current and long-term budget realities.

Our firm's litigators have extensive experience in matters as diverse as patent infringement, trade secret misappropriation, disputes over agreements for employee invention assignment, license disputes, invention ownership disputes arising from joint research and development projects, trademark infringement and counterfeiting, and copyright infringement.

Our IP litigation services include:

  • Pursuing litigation to protect IP rights in federal and state courts across the country
  • Participating in alternative dispute resolution (ADR) activities to reach resolutions at a lower cost
  • Defending against claims accusing clients of infringement or other improper actions
  • Pursuing appeals from errors at trial
  • Providing advice on resolving disputes without engaging in litigation

In addition to their own legal and technical backgrounds, our litigators draw on the full technical expertise of our firm's other lawyers and technical specialists to tailor the staffing of matters to clients’ particular needs.
