Microsoft today won a U.K. ruling invalidating Motorola Mobility Holdings Inc.â€™s patent protection for technology synchronizing message statuses across multiple devices.
Microsoft itself files the case against Motorola Mobility in London a year ago in a pre-emptive bid to invalidate the patent before it could be sued for infringement.
The 2002 patent centred on synchronizing messages to multiple devices, and would have impacted Microsoftâ€™s Live Messenger instant-messaging system and Exchange ActiveSync protocol.
Judge Richard Arnold said in a decision in London today the technology was obvious to experts in the field at the time and should not have been issued.
â€œThe patent is invalid and should be revoked,â€ Arnold said during a 30-second hearing after a week-long trial. â€œSome claims in the patent â€œadd nothing inventive in my view,â€ he said.
Microsoft is currently embroiled in a court case addressing similar patents in Germany, and Apple recently lost a case against Motorola using the same invalidated patent.
â€œWeâ€™re pleased the court granted our request to invalidate Motorolaâ€™s patent and welcome yet another step toward clarifying the cases between our companies,â€ David Howard, Microsoftâ€™s deputy general counsel, said in an e-mailed statement.
