NEW YORK (AP) - A software company allied with NTP Inc., the small firm suing the maker of the BlackBerry devices for patent infringement, has opened another front in the tangled battle over wireless e-mail patents.
Visto Corp., which provides e-mail software to cell-phone companies, said Tuesday that it filed a patent infringement suit against Good Technology Inc., a provider of similar services for smartphones and other handheld devices.
Visto, which is based in Redwood Shores, Calif., claims Good Technology infringes on four patents granted between 1999 and 2004 that cover communication between a device and a larger network. The suit was filed in federal court for the Eastern District of Texas.
