CAFC Affirms District Court Ruling for Amazon on Claim Construction
Last week, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed the United States District Court for the Northern District of California’s final judgment of noninfringement of SpeedTrack’s (Plaintiff-Appellant) patent U.S. Patent No. 5,544,360 (the ‘360 patent). SpeedTrack sued online retailers AMAZON.COM, BESTBUY.COM, LLC, OFFICEMAX, INC., MACY’S, INC., MACYS.COM, LLC and many others for infringement of its category-based filing system. The ultimate decision weighed on the district court’s construction of claims and whether or not the ‘360 patent had a hierarchical structure. The district court construed the claims to not have a hierarchical structure and determined that defendants-cross-appellants did not infringe. The CAFC, with Judge Prost writing for the court, agreed.
