Ethicon sued Covidien in the Ohio district court for infringement of utility and design patents directed to ultrasonic surgical shear devices. The court granted Covidien’s motions for summary judgment, concluding that one patent was invalid as indefinite, that another patent was not infringed by Covidien’s products, and that several design patents were invalid as functional and were not infringed. Ethicon appealed the judgment to the Federal Circuit. The Federal Circuit reversed on indefiniteness, reversed the district court’s determination that Ethicon’s design patents were invalid as primarily functional, and vacated the summary judgment of non-infringement for a surgical shears patent.
