Finjan LLC v. SonicWall, Inc., No. 22-1048 (Fed. Cir. 2023)
Annotate this Case
Finjan asserted the “Downloadable Patents” and the “ARB Patent,” among others in a patent infringement complaint as to SonicWall’s Gateways, Email Security products, and Capture Advanced Threat Protection, among other products. The Downloadable Patents relate to ways to protect network-connectable devices from undesirable downloadable operations.
The district court agreed with SonicWall’s interpretation of the claims, concluding that the recited claim limitations “must be performed by the same computer.” Capture ATP and Gateways and Capture ATP and ES products involve separate, remote computers. The court granted summary judgment of noninfringement. Finjan unsuccessfully argued that there remained a factual dispute as to whether Capture ATP and its Gateway and Capture ATP and its ES products each work together to act as a unified computer system to form the steps as Finjan alleged. The district court excluded the apportionment opinions of Finjan’s technical expert and of Finjan’s damages expert based on that apportionment analysis.
The Federal Circuit vacated in part. The district court based its judgment of invalidity on a collateral estoppel decision that has since been vacated. The court affirmed the summary judgment of noninfringement and the exclusion of Finjan’s expert analysis.
