Patent & Trade Secret Litigation

"This firm's full-service IP practice handles work in the USA and abroad, and is particularly noted for its prowess in patent and trade secret disputes." – Chambers USA

Our IP lawyers handle sophisticated litigation and trials in all IP subjects, with particular expertise in complex patent and trade secret proceedings in U.S. district and state courts, patent trials in the ITC and in arbitrations, as well as infringement, nullity and opposition hearings in a host of European tribunals. Our lawyers are equally adept in the  preparation and prosecution of strategically important patent and trademark applications, and copyright registrations. 

Our experience extends to trials before state courts, U.S. District Courts, the U.S. Court of Appeals for the Federal Circuit, the U.S. International Trade Commission, and the Judicial Panel on Multidistrict Litigation, as well as numerous arbitration and mediation proceedings, particularly under the WIPO and AAA rules. 

We have also engineered comprehensive programs for protecting and enforcing valuable and well-known trademark and trade-dress rights for many famous luxury goods, computer and consumer product companies, including anti-counterfeiting actions in the courts and through U.S. Customs actions.

Our litigators have decades of experience trying patent infringement matters in the courts, the ITC and at the PTAB. These complex cases require the experience our attorneys offer, from knowledge of the technology to the experience in the running of the day-to-day efforts in the multi-party, fast-track litigation.  Our IP lawyers are also highly experienced in directing IP-related proceedings abroad. We routinely partner with local counsel in a large number of foreign countries to direct and coordinate protection and enforcement of our clients' important IP rights around the world (including trials seeking preliminary relief and/or cross-border injunctions), as well as nullity, cancellation and opposition proceedings in various courts, patent tribunals and patent offices throughout the world.

Our IP litigators are also experienced in the supervision, management  and trial of large, complex civil patent cases - efficiently handling the burdens of enormous discovery in highly contentious litigations, and working closely with technical consultants, experts and in-house counsel to effectively and efficiently further the interests of our clients.  We continually explore state of the art technologies to help us organize and manage discovery and trial materials, design exhibits and communicate with our clients.  We have extensive experience in conducting Markman hearings and achieving successful results that are carried forward into winning summary judgment and other case-dispositive motions to significantly reduce or eliminate the issues remaining for trial. In fact, our lawyers have achieved summary judgment of an entire case in our clients' favor, and on several occasions have obtained the affirmative grant of summary judgment of patent infringement on JNOV decisions in favor of our clients. While we have been particularly effective in utilizing carefully focused motion practice to reduce or eliminate costly discovery and trial issues and burdens, in those cases that have gone to trial, our lawyers have been successful in achieving highly favorable jury verdicts and judgments.
