i4i v Microsoft: Petition for Writ of Certiorari Filed

TORONTO, August 28, 2010 - Today, as expected, Microsoft filed a petition for a writ of certiorari,
seeking a review of the i4i v Microsoft patent infringement case by the
Supreme Court of the United States. The Supreme Court has complete discretion
to determine whether or not it will review the case.

Loudon Owen, Chairman of i4i, says, "This next step of filing a petition
was anticipated — indeed, proclaimed for months by Microsoft. We continue to
be confident that i4i will prevail."

In March 2007, i4i sued Microsoft for willful infringement of its United
States Patent 5,787,449 ('449). On May 20, 2009, the jury found i4is Patent
'449 valid and infringed, and awarded Microsoft to pay damages to i4i. On
August 11, 2009, The Honorable Leonard Davis issued a Final Judgment against
Microsoft that included both an award of damages in excess of $290 million
USD to i4i, and a Permanent Injunction, which took effect on January 11,
2010. Microsoft unsuccessfully appealed the decision to the Court of Appeals
for the Federal Circuit late last year, and also unsuccessfully sought a
rehearing of the decision of the Court of Appeals earlier this year.

i4i is a global technology company headquartered in Toronto, Canada. For
