Juniper Evades Finjan Malware Protection Patent Claims

Written June 3, 2019

The US District Court for the Northern District of California on May 29, 2019, held that Juniper Networks Inc., an American networking products developer, did not infringe Finjan Inc.’s malware protection patents. Finjan, Inc. v. Juniper Network, Inc., N.D. Cal., No. 3:17-cv-05659, 5/29/19.

Finjan owns US Patent Nos. 6,804,780 and 8,141,154; the ‘154 patent covers a method for protecting a computer from conventional and “dynamically generated” viruses while the ‘780 patent covers generating an ID for a downloadable to match it against “previously encountered suspect downloadables.”

Finjan accused Juniper of infringing the patents with several technologies. The Court found the term “content processor” in the ‘154 patent to mean “a processor that processes modified content,” and found that Juniper’s products didn’t infringe because they only processed unmodified content.
