Cybersecurity company Carbon Black filed for an IPO on April 9—the same day that Finjan Holdings, Inc. announced that it had entered into a patent license and settlement agreement with the company. According to an 8-K filed by Finjan, Carbon Black has agreed to pay Finjan $3.9M in license fees; further, upon acquisition of Carbon Black, or acquisitions by the company, additional one-time payments, equal to 8% of the gross revenue of certain qualifying products for the four concluded quarters preceding the acquisition, will be due to Finjan. The agreement resolves a patent infringement suit filed by Finjan against Carbon Black on March 21. It also follows a string of multi-million dollar settlements in Finjan’s anti-malware campaign, including one signed in Q1 with Symantec for up to $110M. Finjan reports having licensed its portfolio to more than 20 companies to date, generating over $350M in licensing fees; it has also indicated to investors that more such deals are in the works.
