Narrative Opinion Summary
In this case, the United States Court of Appeals for the Federal Circuit reviewed a summary judgment from the Southern District of New York regarding alleged patent infringement by Benetton Group SpA against V-Formation, Inc. The suit involved V-Formation's U.S. Patent Nos. 5,803,466, 6,045,143, and 5,873,584, which pertain to modular skate construction. V-Formation alleged infringement of these patents by various Benetton roller skate models. The district court granted summary judgment in favor of Benetton, finding noninfringement of the '466 and '143 patents and invalidating the '584 patent's claims. The appellate court conducted a de novo review of the claim construction, focusing on the term 'releasably attaching' from the '466 patent. It affirmed the lower court's interpretation that the term required fasteners permitting easy removal and replacement of skate sidewalls, concluding that rivets did not meet this criterion. Consequently, the court upheld the noninfringement ruling, holding that the accused devices did not fulfill all claim limitations. Furthermore, the court dismissed the applicability of the doctrine of equivalents, as the rivets did not serve the same function as the claimed fasteners. The decision affirmed that no material factual disputes existed regarding the structure of the toe and heel plates in the accused skates, and each party was ordered to bear its own costs.
