Palo Alto Networks asked a Virginia judge to dismiss a patent lawsuit filed against them by Centripetal Networks, questioning the broad nature of the covered technologies and processes and saying the company has not put forth any plausible evidence that their products are being copied. In an April 30 court filing, lawyers for Palo Alto Networks claim Centripetalâs initial 146-page complaint âmakes no genuine attempt to tie a complete asserted claim to any particular accused product.â The suit cites 12 specific patents, most dealing with filtering network traffic, and points to seven Palo Alto products that violate those patents. But Palo Alto’s legal team claims the charges amount to âdisorganized assertions interspersed with claim language that provide no indication of how the features of the accused products allegedly satisfy the elements of the asserted claims.â
