In 2018, shortly after the announcement of Super Smash Bros. Ultimate for the Nintendo Switch, the company added support for the Wii U GameCube controller adapter for the newer hybrid console. Legal issues Anascape Ltd, a Texas-based firm, filed a lawsuit against Nintendo for patent infringements regarding Nintendo's controllers. A July 2008 verdict found that a ban would be issued preventing Nintendo from selling several controllers, including the WaveBird, in the United States. Nintendo was free to continue selling the WaveBird pending an appeal to the U.S. Court of Appeals for the Federal Circuit. On April 13, 2010, Nintendo won the appeal and the previous court decision was reversed.
