TORONTO - In i4i v. Microsoft, Defendant-Appellant Microsoft filed its Opening Brief in the United States Court of Appeals for the Federal Circuit Tuesday night.

Loudon Owen, Chairman of i4i, says, "The appeal brief filed by Microsoft is an extraordinary document. It captures the hostile attitude of Microsoft toward inventors who dare to enforce patents against them. It is also blatantly derogatory about the Court system."

Founded in 1993 (just 18 years after Microsoft was founded), i4i was formed to change the way information is managed worldwide. Mr. Owen continues, "We sought and received the protection of the court so we can compete on a level playing field, and run our business without infringement by the Defendant Microsoft. Microsoft was proven to have willfully infringed on i4i's patent."

Mr. Owen says, "We do not have the gargantuan financial resources of Microsoft, but i4i has the protection of fairness under the U.S. justice system. Microsoft is not above the law. It cannot privately expropriate i4i's patented invention."

"We firmly believe the decision of the jury and judge in the United States District Court for the Eastern District of Texas was correct on the facts and we shall prevail on appeal," says Mr. Owen.

i4i's responding brief is due on September 7, 2009.
