Patent Litigation

Patterson Belknap has litigated “bet-the-company” patent disputes for decades. We have handled some of the most notable patent cases and our clients have received some of the largest awards and settlements of patent cases ever. For instance, after a series of related trials involving a ground-breaking patent, we obtained judgments and settlements for our client totaling $3.6 billion, including in 2010 a settlement of $1.725 billion, one of the largest settlements ever of a patent infringement case in the United States.

We are ranked among the top firms in New York for patent litigation by Chambers USA: America’s Leading Lawyers for Business. The guide notes, “This team of attorneys combines exceptional scientific knowledge with terrific trial skills.” Our team “receives the most widespread acknowledgement for its performance in high stakes patent litigation” and is “particularly strong on life sciences patent litigation.” U.S. News - Best Lawyers® "Best Law Firms" also ranked us among the top-tier patent law firms both nationally and in New York City.

Many of our attorneys have scientific and technical backgrounds as well as industry experience in fields such as chemistry, biochemistry, biology, biotechnology, statistics, mathematics, electro-mechanical computer technology, metallurgical engineering, electrical engineering, semiconductor manufacturing, electro-optical circuits and associated software.

We have tried numerous cases in various district courts across the country and have handled numerous arguments before the Court of Appeals for the Federal Circuit. We also have tried cases before the International Trade Commission and are actively involved in post-grant review proceedings before the U.S. Patent and Trademark Office. We have conducted U.S. and international arbitrations in this country and abroad, and have supervised and worked with foreign counsel on patent litigation matters. In addition, we regularly negotiate patent licenses and provide opinions concerning patent validity and infringement. Our willingness to go to trial (when in the client's interest), and ability to assess realistically the strengths of a case, not only serve our clients in court but also can increase the chances for a favorable outcome out of court.
