The lawsuit, filed in the US District Court for the District of Delaware, claims that the three companies are infringing Finjan's intellectual property.
The suit also seeks an injunction against Secure Computing, CyberGuard and Webwasher preventing continued sales of the Webwasher Secure Content Management software suite, and damages for wilful infringement of Finjan's intellectual property.
Finjan claims to have several of the earliest patents covering various aspects of web security.
The intellectual property in the current patent infringement case involves systems and methods for protecting a computer and a network from hostile 'downloadables' and/or malicious code, with a priority date of 8 November 1996.
