Just to clarify things, Fender is going after this through copyright (ala as an artistic piece of work) and not trademark (ala Gibson). Hilariously the German law firm for FMIC claimed that the 1954 Stratocaster was inspired by Cadillac's and Mustangs of the time, except that the Mustang wasn't first made until 1964.
KDH goes over it in his video.
