<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Waterloo, Ontario &#151; 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 &#147;Patent
Office&#148;) 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. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>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. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Although NTP may appeal, the
rejections reflect the final opinion of the Patent Office&#146;s Central Reexamination
Unit that the 3 patents at issue in this case are invalid. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>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. </FONT></P>
