How Apple v. Samsung Was Explained To the Jury

Fender did not pursue the Strat-clone manufacturers in court; and then after attempting to trademark the iconic Stratocaster contours decades later, a court ruled in 2009 that "the body shapes were generic and that consumers do not solely associate these shapes with Fender Musical Instruments Corporation". The ruling went so far as to say "in the case of the [Stratocaster] body outline, this configuration is so common that it is depicted as a generic electric guitar in a dictionary."

That's a very good analogy.
