The US Supreme Court will not review the Blackberry patent infringement dispute between RIM and NTP - a blow to RIM's hopes.

NTP is suing RIM for alleged infringement of patents covering the operation of a wireless e-mail service. An injunction against RIM could force the company to shut down the BlackBerry service or find a technical workaround to avoid the contested technology. The companies last year reached a settlement in the case, but it fell apart soon after.

RIM sought to have the Supreme Court review issues involving the cross-border reach of US patent law. The court declined to review them.
