Comments on Patent Complaint by Visto </B></FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2><B><I>Waterloo,
Ontario</I></B><I></I> &#150; Research In Motion Limited (RIM) (Nasdaq: RIMM; TSX: RIM)
today learned that a complaint alleging patent infringement has been filed in the U.S.
Eastern District Court of Texas by Visto Corporation against RIM. Visto is alleging
infringement of four patents (#6,023,708, #6,085,192, #6,151,606 and #6,708,221) and
seeking an injunction and monetary damages. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>Visto has already filed patent
complaints against several companies in the industry, including Microsoft, Good
Technology, Smartner and Sproqit. Visto filed its complaint against RIM immediately
following a jury verdict in its litigation against Seven Networks. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>RIM has been monitoring Visto&#146;s
litigation against other companies in the industry and, based on prior art and actual
products in market, RIM believes Visto&#146;s patents are invalid. Further, Visto&#146;s
patent claims as directed against Seven Networks refer to a different type of system than
RIM&#146;s technology. RIM believes it does not infringe Visto&#146;s patents and will
file its legal response in due course. In addition to challenging validity and
infringement, RIM will now also consider asserting its own patents against Visto. </FONT></P>

<!-- MARKER FORMAT-SHEET="Para Flush" FSL="Default" -->
<P><FONT FACE="Times New Roman, Times, Serif" SIZE=2>RIM is fully prepared and equipped to
deal with the matter and will continue to disclose material information as it becomes
available. RIM does not expect its customers to be impacted by Visto&#146;s complaint and,
given the status of Visto&#146;s current litigation with other companies, it is unlikely
that any material court proceedings in this litigation could begin prior to the middle of
calendar 2007. </FONT></P>
