Another NTP Patent Invalidated

darkmeridian writes "Bloomberg reports that the PTO has granted a non-final rejection of a third NTP patent asserted against Research in Motion in the Blackberry litigation. Five patents have been asserted against RIM, and only one of the three rejected has been found to be valid and infringed. Yet this development helps RIM as it seeks to avoid an injunction against operation of the Blackberry network pending appeal."
