On January 10, 2018, the Federal Circuit added Finjan, Inc. v. Blue Coat Sys., Inc., No. 2016-2520 (Fed. Cir.), to its Enfish jurisprudence and upheld the subject matter eligibility of a software patent directed to virus-scanning downloadable app code for known and suspected malware. As construed, the invention claims novel behavioral-based analysis of source code to identify; detection of potentially dangerous files results in creation of a new file attached to the app code which is then evaluated by the destination computer to determine whether to allow the app to be downloaded.
