Winston & Strawn LLP

Winston & Strawn LLP has built a reputation as a trial lawyers’ firm. Our litigators are some of the most seasoned in the industry, bringing extensive courtroom experience to every matter our firm handles. Moreover, our long history of taking cases to trial – and winning – gives our clients tremendous settlement leverage with their adversaries, as well as confidence in a successful outcome if and when they go to trial. More than 25 of our attorneys have first-chaired multiple patent trials, and in the past five years we have taken 43 patent cases to trial.

National recognition

With approximately 130 attorneys, Winston’s patent litigation practice is one of the most active and highly regarded in the country. Most recently, Winston was recognised for its excellence in IP litigation (United States – Tier 1) by Benchmark Litigation. In 2018 our IP litigation practice was once again ranked in the first tier nationally by US News & World Report in its Best Law Firms survey, and both Chambers USA and The Legal 500 selected our IP practice for national rankings.

US district court litigation

ITC litigation

Collectively, Winston has more than 80 years’ experience litigating high-stakes patent infringement cases before the International Trade Commission (ITC). The firm’s experienced team comprises a number of attorneys who have first-chaired successful ITC trials, as well as a former ITC senior investigative attorney, a former ITC attorney adviser to the chief administrative law judge and former US patent examiners. Our attorneys have the education and industry experience to immediately understand complex technology, a working knowledge of the specialised procedural law and the substantive experience to formulate and execute the strategies necessary to succeed at the ITC.
