The court addressed an appeal regarding a motion to compel responses from the Plaintiffs during the discovery process in a patent infringement lawsuit. The Defendant sought to obtain structural drawings of the Plaintiffs’ tools to determine potential infringement. The Case Management Judge dismissed the motion, concluding that the requested information was irrelevant to the litigation. On appeal, the court evaluated whether the dismissal was justified. It reaffirmed that a patentee can recover damages for losses stemming from infringement, not limited to lost sales of products covered by the patents. The judgment clarified that damages include all losses due to infringement, such as those from products not expressly claimed in the patents.
