A patent-holding company has petitioned a Texas federal judge for a new infringement trial against DoorDash, alleging that the food delivery company’s conduct resulted in “prejudicial errors.” The request also seeks a favorable judgment on the enablement defense.
In July 2026, a jury in the U.S. District Court for the Eastern District of Texas found that the plaintiff failed to prove infringement of the asserted patent claim, leading to a complete victory for DoorDash. The trial, presided over by Judge Robert W. Schroeder III, concluded with the jury siding entirely with DoorDash. The defense was represented by King & Spalding, who successfully argued that the plaintiff’s patent, originally filed in 2002, pertained to an older network communications architecture fundamentally different from DoorDash’s approach. Additionally, the defense team effectively challenged the plaintiff’s damages theories, reducing the claimed damages from approximately $1.5 billion before trial to $38 million at trial.

The plaintiff’s motion for a new trial underscores the ongoing complexities in patent litigation, particularly in the rapidly evolving technology sector. The outcome of this motion could have significant implications for both parties and may influence future patent infringement cases within the industry.
