Patent Litigation Profile: U.S. District Court for the District of Delaware

Court Overview

The United States District Court for the District of Delaware, located in Wilmington, is a premier venue for patent litigation in the United States. As part of the Third Circuit, its patent case decisions are appealed to the U.S. Court of Appeals for the Federal Circuit. For years, it has been one of the nation's busiest patent dockets, frequently ranking as the first or second most active district for new patent case filings. The court's prominence is largely due to Delaware's status as the state of incorporation for a majority of U.S. public companies and Fortune 500 corporations, making it a proper venue for infringement suits against them, particularly after the Supreme Court's 2017 TC Heartland decision narrowed venue options.

Reputation and Practices

The District of Delaware is known for its experienced judiciary and sophisticated management of complex patent cases, rather than for being a "rocket docket." The median time to trial is approximately 24 to 30 months. The court's judges generally give substantial weight to a plaintiff's choice of forum, making motions to transfer out of the district a challenge, especially when the defendant is incorporated in Delaware. The court, particularly in pharmaceutical patent disputes (ANDA cases), has a reputation for preferring full bench trials to resolve complex factual disputes over granting summary judgment, ensuring a thorough record for appeal. Delaware has long been the dominant venue for these ANDA cases, handling more than all other U.S. courts combined for over a decade.

Local Rules and Procedures

Unlike other popular patent venues, the District of Delaware has not adopted a comprehensive set of local patent rules. Instead, patent case management is governed by the court's general local rules, a "Default Standard for Discovery," and, most importantly, the individual practices and detailed form scheduling orders of the assigned judge. In April 2022, Chief Judge Colm F. Connolly issued influential standing orders applicable to cases before him that have significantly impacted patent litigation practice. These orders require parties to disclose detailed information about third-party litigation funding arrangements and to identify all owners and partners up the corporate chain until every entity and individual with an interest is revealed. These disclosure requirements have been credited with a subsequent decrease in patent lawsuit filings in the district.

Notable Rulings and Judges

The court handles a heavy load of patent disputes, including numerous cases involving frequent litigants such as AlmondNet, Inc., Disintermedation Services Inc., and Datonics LLC, as reflected in this site's tracked cases. Chief Judge Connolly's standing orders on corporate and funding transparency represent one of the most notable recent developments from the court, demonstrating a focus on exposing the real parties of interest in patent assertion campaigns. Other prominent judges with significant patent experience include Judge Richard G. Andrews and Judge Maryellen Noreika, both of whom regularly preside over patent trials. The court's four active district judges and four magistrate judges are assisted by a number of visiting judges to manage the demanding caseload.
