Finjan Holdings Inc. (FNJN), the cybertechnology and licensing company run by CEO Phil Hartstein, said it will be able to proceed to trial on alleged infringement of six of eight patents against Proofpoint Inc. after a federal judge ruled on motions for summary judgment.

Judge Haywood Gilliam Jr. on April 12 entered his order granting In part and denying in part each side’s motions for summary judgment. The judge ruled that triable issues of fact exist as to six of the eight asserted patents against Proofpoint and Armorize products, to be tried by jury.

East Palo Alto, Calif.-based Finjan said the trial is set for June 13.

The six patents are U.S. Patent Nos. 6,154,844; 7,058,822; 7,647,633; 7,975,305; 8,079,086; and 8,224,408, which cover cloud, endpoint, web and messaging security, and networking and perimeter defense technologies. Finjan U.S. Patent Nos. 7,613,918 and 8,141,154 will not be included in the trial without any change to their validity.

"The court's order has streamlined our case against Proofpoint without any significant impact to our damages case," said Julie Mar-Spinola, Finjan's chief intellectual property officer in a statement. "We remain confident in the merits of our patent claims and will proceed to trial accordingly.”

Jennifer Kash, a partner with Quinn Emanuel Urquhart & Sullivan LLP in San Francisco, who represents Proofpoint, couldn’t be reached for comment.
