Visto sues Microsoft, patent infringement

Dec 15 2005 - 01:17 PM ET | Data

Fresh off its patent licensing pact with NTP, Visto filed suit against Microsoft for patent infringement. This is nothing new for Microsoft--the company typically has 30 ongoing patent infringement lawsuits going on at any given time--but is notable because it's yet another patent battle in the wireless email space.

For their foray into mobile email and data access, Microsoft simply decided to misappropriate Visto’s well known and documented patented technology.

Visto holds 25 patents and has 57 more pending. Terms of Visto's agreement with NTP were not disclosed, bt the Wall Street Journal notes [sub req.] that NTP at least got an equity stake.
