Prior to launching the device, Apple received a license to the name "Mighty Mouse" from Viacom, and subsequently CBS Operations, as owner of the Mighty Mouse cartoon series, the title having been registered in the U.S. as a trademark with respect to various merchandise (such as T-shirts and multivitamins) associated with the character. However, the trademark did not cover computer peripherals, and CBS did not apply to trademark the term in the U.S. with respect to computer mice until mid-2007.On May 21, 2008, it was announced that Man & Machine Inc., a supplier of keyboards and mice to laboratories and hospitals, had sued Apple Inc. for trademark infringement over its use of the name Mighty Mouse. Man & Machine Inc. had four registered or pending trademarks on various computer pointing related technologies, including "Cool Mouse", "Really Cool", and "Man and Machine and Design". The particular Mighty Mouse trademark in dispute was first filed by Man & Machine Inc., on December 18, 2007 with the description "Computer cursor control devices, namely, computer mice" ? after CBS's filing, but claiming first use in 2004, before the introduction of the Apple device.Following opposition proceedings on both sides against the other, CBS subsequently withdrew its application, allowing Man & Machine to register the U.S. trademark for computer mice. As a result, Apple stopped selling mice under the "Mighty Mouse" name on October 20, 2009, when it introduced the wireless Magic Mouse and renamed the existing wired mouse the "Apple Mouse".Incidentally, CBS was successful in registering "Mighty Mouse" as a trademark for computer mice in some other countries, including Canada, although Apple nevertheless chose to change its product name internationally.
