RIM wins patent battle in UK courtroom

Comments

Nothing but good news is slowly seeping out of Research In Motion’s camp. First we get the release date for the 8800 (by no intention of theirs, really), and now we’re happy to let you know that RIM has settled patent issues in the UK with a notch in the win column, says Bloomberg.

The Court of Appeal in London today said Research In Motion hasn’t infringed a U.K. patent held by Luxembourg-based Inpro Licensing Sarl. Inpro’s patent, which relates to how portable computers surf the Internet, isn’t valid and must be revoked, the appeals court said.

The decision protects Research In Motion’s service to hundreds of thousands of subscribers in the U.K. as the Waterloo, Ontario-based company seeks to fend off competition from new products like Apple Inc.’s iPhone and Cingular Wireless’s BlackJack.

Inpro, which makes money from licensing a portfolio of intellectual property, lost the first round of the case last February, prompting today’s appeal. The company also last year lost a similar German lawsuit against Research In Motion and BlackBerry reseller T-Mobile International AG.
