Firm Details


Desmarais LLP is a trial boutique focused on the litigation of complex, often technology-driven disputes.  Its lawyers have successfully tried some of the most important intellectual property disputes in recent times, for some of the largest companies in the world.  The firm also handles significant appellate matters, having argued the appeal of numerous cases that have shaped the substantive direction and development of intellectual property law.


Desmarais LLP represents a diverse set of clients in a wide variety of technology areas.  Its clients include Fortune 100 companies who rely on the firm to protect their most important intellectual property assets, and also to defend them against claims that jeopardize their critical business interests.  In addition, Desmarais LLP represents smaller entities, including individuals, who seek to enforce the exclusive rights in their inventions or technology. 

Intellectual Property Litigation

Desmarais LLP handles all stages of litigation, and the firm’s attorneys have significant trial experience in every major forum for technology disputes in the United States.  Desmarais LLP’s attorneys have successfully tried cases before juries and judges throughout the country, as well as before administrative bodies (including the International Trade Commission) and arbitration panels.  At the appellate level, Desmarais LLP’s attorneys have successfully briefed and argued cases before numerous appellate courts, including the Court of Appeals for the Federal Circuit.

Desmarais LLP and its lawyers consistently have been recognized in industry publications as leaders in its areas of practice, and virtually all are technically trained, with degrees in engineering or the sciences.  In addition, the firm boasts an unusually deep bench of lawyers with actual, real-world jury trial experience, particularly in the nation’s busiest districts for patent litigation.  Whether for jury trial, bench trial, or appellate argument, in whatever jurisdiction, Desmarais LLP’s focused approach will bring a lean team of experienced and creative professionals dedicated to achieving their client’s business goals.

Although the firm’s cases span a wide range of subjects, Desmarais LLP’s practice centers on technology-related disputes.  Its lawyers have achieved successful trial results for firm clients in dozens of patent infringement cases, concerning technologies as diverse as semiconductors, telecommunications and networking, computer software, consumer electronics, pharmaceuticals, medical devices, biotechnology, chemicals, and transportation.  On appeal, Desmarais LLP has preserved both offensive and defensive victories for its clients in various subject matter areas, obtained reversal of adverse results, and steered the development of substantive law in its clients’ interests.

Desmarais LLP’s technology litigation expertise extends well beyond patent infringement cases.  The firm’s attorneys have also successfully litigated, for both plaintiffs and defendants, a wide variety of other types of technology-driven disputes, such as those involving antitrust, unfair competition, trade secret, fraud, and contract claims.  Further, even beyond technology matters, the firm’s attorneys have also built a strong track record of litigation success in other intellectual property areas. For example, its attorneys have successfully conducted trials and appeals in high profile trademark, trade dress, and counterfeiting matters.


Innovative Fee Structures
In addition to Desmarais LLP’s record of success, its flexible and innovative approach to fee arrangements sets it apart from other top-tier firms that handle the same types of large, complex litigations.  The firm has abandoned the traditional (and frequently inefficient) billable-hour approach in favor of fee arrangements more nearly tailored to its clients’ interests.  For clients who want predictability, the firm’s fee structures will accommodate a flat fee negotiated at the outset.  For those interested in a shared-risk approach, Desmarais LLP is open to contingent fee arrangements and hybrid fee structures tailored to meet the needs of its clients and the case.
