The U.S. Patent and Trademark Office has issued a final rejection of one of the five patents at issue in NTP’s long-running case against BlackBerry maker Research In Motion. The final rejection was posted on the Patent Office’s Web site for the NTP-held patent, which covers a system for sending emails over a wireless network to a mobile device. The Patent Office has already issued nonfinal actions rejecting the claims in four out of the five NTP patents in question, but a final rejection is required before the appeals process can begin. RIM issued a statement confirming it had received the final action and said it expects the rejections to withstand future NTP appeals.
