Research In Motion agreed to pay rival Visto $267.5 million to license and buy patents, settling a long-running legal battle.
As part of the deal, RIM received a perpetual and fully paid license on all Visto patents and acquired some Visto intellectual property. The companies also dropped all outstanding lawsuits.
The deal closes a legal battle that started just after RIM settled a disagreement in 2006 with NTP that threatened to shut down BlackBerry phones.
RIM agreed to pay NTP $612 million after NTP asked the court for an injunction that would have halted email delivery to the phones.
Visto, which recently bought mobile email provider Good Technology from Motorola, has sued several other mobile e-mail providers, including Seven Networks and Microsoft. Both companies settled the lawsuits. Visto also sued Good before buying the company.
In 2006, Daniel Mendez, a Visto cofounder, said that the lawsuits were an indication of the growing demand for mobile email. A few companies are technology pioneers in the segment, but new competitors have only recently taken notice because of the market potential, he said at the time.
