Narrative Opinion Summary
In a patent infringement dispute, Jack Guttman, Inc. appealed the Southern District of Ohio's denial of a preliminary injunction against Kopykake Enterprises, Inc. regarding U.S. Patent No. 6,319,530 B1. The patent pertains to a method for printing images on edible substrates for cake decoration. The district court had construed key claim terms, including 'non-tortuous copy path' and 'photocopy machine,' in a manner unfavorable to Guttman, leading to the denial of the injunction based on an unlikely success on the merits. The United States Court of Appeals for the Federal Circuit vacated this decision, finding that the district court misapplied the patentee's definitions provided in the patent specification and prosecution history, thereby abusing its discretion. The appellate court emphasized the need for accurate claim construction and remanded the case for further proceedings, including a reevaluation of the likelihood of infringement and consideration of all factors required for a preliminary injunction. The decision underscores the importance of adhering to intrinsic evidence in patent claim interpretation and the discretionary nature of granting preliminary injunctions.
