Rex Medical's patent fight with Intuitive Surgical gave damages experts another post-EcoFactor data point in 2025.
The accused products included Intuitive surgical staplers and reloads. The appeal addressed reasonable-royalty proof and the degree to which expert methodology was tied to the facts of the case.
For medical-device litigants, the case is commercially important even when it does not rewrite damages law. Product-specific proof, comparable data, and the expert's link between economics and infringement remain central.
The story also belongs in the trial-practice archive because damages admissibility became a recurring Federal Circuit theme throughout 2025.
