NTP wins 30-day extension to file case in patent row with RIM

Comments

NTP Inc has won a 30-day extension from the US Patent and Trademark Office, giving it more time to file a defense of patents at the center of its long-running battle with BlackBerry-maker Research In Motion Ltd (RIM), the Wall Street Journal reported.

In its online edition, the newspaper said the delay gives NTP lawyers more time to respond to the patent office’s rejection of some of its patent claims.

The claims are key to a court dispute that could lead to the shutdown of the BlackBerry wireless email service in the US.

A US court is set to consider imposing a US ban on Blackberry at a hearing after Feb 1. RIM said it has developed ‘workaround’ technology to bypass a possible injunction.

A patent-office spokesman said the office is re-examining NTP’s case and will issue a decision within six to 10 weeks.
