RIM Provides Update on Patent Reexamination Proceeding


All Patents Remaining In Dispute Have Been Rejected

WATERLOO, ONTARIO, Feb. 24, 2006, Research In Motion (RIM) (NASDAQ:RIMM)(TSX:RIM) confirmed today that it has received a copy of a Final Office Action issued by the U.S. Patent and Trademark Office (the “Patent Office”) in the ex parte reexamination of NTP, Inc. Patent #5,436,960. This Final Office Action maintains the outright and complete rejection of all claims in the patent.

All of the 3 patents remaining in dispute in the NTP vs. RIM litigation have now been rejected based in part on prior art not considered in the 2002 trial in the United States District Court for the Eastern District of Virginia.

Although NTP may appeal, the rejections reflect the final opinion of the Patent Office’s Central Reexamination Unit that the 3 patents at issue in this case are invalid.

The final rejections were all based on multiple grounds, required unanimous agreement from a panel of 3 senior patent examiners and are expected to withstand all future appeals by NTP.

1) Patent #6,317,592 contains 6 of the 9 claims at issue in this case and all 6 claims were rejected in the Patent Office ruling disclosed by RIM on February 1, 2006.

2) Patent #6,067,451 contains 2 of the 9 claims at issue in this case and both claims were rejected in the Patent Office ruling disclosed by RIM on February 22, 2006.

3) Patent #5,436,960 contains the last of the 9 claims at issue in this case and that claim was rejected in the Patent Office ruling disclosed today.
