Symantec filed a second patent infringement lawsuit against Zscaler in the US Federal District Court for the District of Delaware. The move comes after the company submitted a patent infringement complaint versus Zscaler on 12 December 2016.

In the new lawsuit filed, Zscaler is accused of illegally using Symantec's patented technology relating to a variety of network security technologies, including web security, security scanning, data loss prevention, intrusion prevention and intrusion signature analysis. The seven patents asserted in the lawsuit filed today pre-date the formation of Zscaler and include six patents that were obtained through Symantec's acquisition of web security market leader Blue Coat Systems, Symantec said in a press release. This lawsuit is based on U.S. Patent Nos. 6,285,658; 7,360,249; 7,587,488; 8,316,429; 8,316,446; 8,402,540; and 9,525,696.
