Protegrity Announces an Update in Patent Infringement Lawsuit Against Voltage Security | SYS-CON MEDIA

In three separate lawsuits, Protegrity sued Voltage, Ingrian/Safenet and nuBridges for infringing Protegrity's U.S. Patent 6,321,201 ('201 Patent). As an attempt to invalidate the '201 Patent, Voltage Security requested the United States Patent and Trademark Office (USPTO) reexamine the '201 Patent on December 1, 2010. Voltage based its Reexamination Request on specific prior art references that Voltage claimed should have prevented issuance of the '201 Patent in the first place.
