i4i v Microsoft: USPTO issued a Reexamination Certificate

Toronto-based tech company i4i Inc., which last year won a $290 million patent verdict against Microsoft over the use of custom XML technology in Word, announced that the U.S. Patent and Trademark Office has issued a Reexamination Certificate which confirms the patentability of all claims of U.S. Patent 5,787,449 ('449) that had been put into the reexamination proceeding by Microsoft. This issuance of the Reexamination Certificate formally concludes the reexamination proceeding favorably for i4i.

In a statement, Microsoft said, "We continue to believe there are important matters of patent law that still need to be properly addressed, and we are considering our options for going forward."
