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