Man & Machine, a Landover, Md., maker of medical keyboards and computer peripherals, said on Tuesday it has filed a trademark-infringement lawsuit against Apple and CBS over the Mighty Mouse name. The company says that it has been selling its Mighty Mouse, "a waterproof optical mouse for medical, industrial, and marine applications," since March 2004. Apple began selling its wired and wireless Mighty Mouse for MAC PCs in August 2005. "This action arises from Apple's use and proposed continued use of the trademark 'Mighty Mouse' in violation of M&M's rights in its own 'Mighty Mouse' trademark," the complaint states. "Apple's use of the 'Mighty Mouse' trademark takes place under color of an agreement with CBS purporting to license such use." M&M is seeking undisclosed damages and a court order preventing Apple from using the name Mighty Mouse for its mice.
