MOUNTAIN VIEW, Calif.–December 12, 2016–(BUSINESS WIRE)–Symantec Corp. (NASDAQ:SYMC) today announced that it has filed a patent infringement lawsuit against Zscaler, Inc. in the U.S. Federal District Court for the District of Delaware.

The lawsuit asserts that Zscaler products violate seven of Symantec’s patents across a variety of network security technologies including web security, data loss prevention, threat prevention, access control and antivirus techniques. This lawsuit is based on U.S. Patent Nos. 6,279,113; 7,203,959; 7,246,227; 7,392,543; 7,735,116; 8,181,036; and 8,661,498.

“We have an obligation to our customers and our shareholders to defend our intellectual property when we believe it has been infringed, and the lawsuit filed against Zscaler is intended to stop them from copying our pioneering technologies in network security,” said Scott Taylor, Symantec’s Executive Vice President, General Counsel and Secretary. “Since 2004, Symantec has invested over $10 billion in R&D to provide our customers with innovative technologies, and much of that investment is protected by our portfolio of more than 2,000 United States patents. Today’s action is a necessary step to defend our valuable ideas and assets that Symantec customers rely on for industry-leading cyber defense.”

Symantec noted that it is continuing to investigate this matter and will file further claims if additional infringements are identified.
