Visto Corporation, a provider of secure push email services, announced today that it has filed a patent infringement lawsuit against Good Technology. The suit, which alleges that Good’s products and services infringe on multiple patents held by Visto, was filed in the U.S. District Court in the Eastern District of Texas.
One should know that Visto has already filed another patent infringement case against Microsoft last month after striking a licensing deal with NTP. The deal also saw NTP becoming a key investor in Visto.
The patents that are in dispute are as follow:
* U.S. Patent No. 5,961,590 titled, “System And Method For Synchronizing Electronic Mail Between A Client Site And A Central Site”
* U.S. Patent No. 6,085,192 titled, “System And Method For Securely Synchronizing Multiple Copies Of A Workspace Element In A Network”
* U.S. Patent No. 6,708,221 titled, “System And Method For Globally And Securely Accessing Unified Information In A Computer Network”
* U.S. Patent No. 6,151,606 titled, “System And Method For Using A Workspace Data Manager To Access, Manipulate And Synchronize Network Data”
In the claim, Visto alleges that various Good Technology products, including GoodLink, their push email service, infringe on the patents that Visto has held for the past nine years. The suit seeks a permanent injunction against GoodLink and Good’s other infringing technology, which can power several mobile devices including the Palm Treo, HP’s iPAQ hw6500, and the Motorola MPx220, among others. The suit also seeks monetary damages.
