When Microsoft Corporation filed a certiorari petition with the U.S. Supreme Court in August seeking to reverse a $290 million patent infringement award won by Canadian software maker i4i Inc., the software giant asked the Court for a ruling that would fundamentally alter the patent litigation landscape.

On Wednesday, Microsoft lined up some major reinforcements—11 amicus briefs filed in support of its bid to have the Supreme Court take the case. Microsoft’s appellate team includes lawyers from Weil, Gotshal & Manges and Gibson, Dunn & Crutcher as well as in-house attorney Andy Culbert.
