About

Provided by Jenner & Block LLP

Jenner & Block’s litigation department differentiates itself through its deep experience and abiding commitment to excellence. With more than 400 litigators and dispute lawyers in five offices, Jenner & Block is a leading practice for the most important litigation and arbitration matters facing companies. The firm’s known reputation and trusted experience for board-level counsel, internal investigations, complex commercial disputes and arbitrations position Jenner & Block to handle its clients’ most sensitive and sizeable matters, including massive disputes that can involve upwards of 1,000 lawyers at any time (including contract lawyers). Over a recent 18-month period, the firm’s lawyers tried more than 125 matters with more than US$30 billion at stake. The media recognized several litigation department successes including the Appellate and Supreme Court Practice’s perfect record during the October 2015 US Supreme Court term, winning seven cases on the merits, and the firm’s winning streak in patent appeals in the Federal Circuit. This track record of victories is evidence of what the firm does best: tries cases and takes them to appeal. Jenner & Block’s work is diverse, remarkable and noteworthy.
