US federal district courts have exclusive jurisdiction over patent infringement claims. Popular districts for patent disputes include the District of Delaware, the Eastern District of Texas, and the Northern District of California. Many districts that regularly hear patent cases have special rules for patent cases. Some districts are known for the rapid pace at which they proceed to trial, while others tend to move at a slower pace. Patent cases usually last between two and four years.
