Cellspin Soft, Inc. v. Fitbit LLC, et al., (Fed. Cir. No. 22-2025), decided 01 Nov 24

The CAFC affirms a district court's grant of summary judgment for Fitbit, Nike, Under Armour, Fossil, Nikon, and Garmin in a patent infringement lawsuit brought by Cellspin Soft, Inc. Cellspin alleged infringement of three patents related to automatically uploading multimedia content via Bluetooth-enabled devices. The appeals court found that Cellspin failed to demonstrate a genuine dispute of material fact regarding several claim limitations, including the requirement of a continuous paired connection and the proper attachment of user identifiers. The court upheld the district court's exclusion of Cellspin's late-introduced evidence. The court ultimately affirmed the judgment of non-infringement for all defendants.
