Fender lost their case on March 26, 2009 after trying to restrict the use of the Stratocaster, Telecaster and Precision Bass body shapes.
In the court case, Fender had targeted the "copycat" designs of guitar manufacturers including, Indoor Storm, Ltd., Jim Triggs Guitars, JS Technologies, Inc., Lakland Musical Instruments, LLC, Levinson Musical Products, Ltd., Michael Tobias Design, SR, Peavey Electronics Corporation, Raise Praise, Inc. d/b/a Tom Anderson Guitarworks, Sadowsky Guitars Ltd., Saga Musical Instruments, Schecter Guitar Research, Inc., Stuart Spector Designs, Ltd., The ESP Guitar Company, Tradition Guitars, Inc., U.S. Music Corp., Warmoth Guitar Products, Inc. and WD Music Products, Inc.and many others as infringing its Stratocaster, Telecaster and Precision Bass designs.
Leo filed a patent in 1954. It protected the design for 14 years and it was not renewed in timely fashion. Beginning in 1968, anyone and everyone could copy those designs, and they did.
The ruling stated:
"The evidence overwhelmingly demonstrates that these configurations are so common in the industry that they cannot identify source. In fact, 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."
