The patent fight between Reserch In Motion (RIM) and Visto is over. The BlackBerry-maker has agreed to pay $267.5 million for a perpetual license to all of Visto's patents. RIM also gains some of Visto's intellectual property.

Visto sued RIM after winning $3.6 million in damages from another wireless e-mail company, Seven Networks, back in 2006, the same year RIM settled a patent dispute with NTP Inc. for $612.5 million. That suit threatened to cut off RIM's mob-e-mail service in the U.S.

Closely held Visto is a white-label wireless e-mail vendor with several hundred thousand customers through wireless carriers in the U.S., and abroad. Operators sell Visto e-mail under their own brand.

Visto's mobile e-mail technology supports over 100 different wireless devices and a wide variety of platforms: Symbian, Windows Mobile, the Palm OS, and J2ME, in addition to WAP browsers.

The settlement is expected to be completed during the week of July 20, 2009 and is subject to certain closing conditions.

Based on preliminary analysis, RIM expects the majority of the payment to be expensed as an unusual item in the second quarter of fiscal 2010, with the remainder being classified as an intangible asset.
