Instruments- discuss specific features, luthiers, instrument problems & questions
@wally-venable - in the patent world, that is called 'making a broad claim'. However, anyone can create something that has a few slight differences and present it as something new. The patent holder would then have to shoulder the expense of legally defending their claim, which is often more trouble and expense than worth doing. In this case, the idea of claiming all possible sizes, shapes, and variations of a simple stringed instrument is patently ridiculous (pun intended).
I'm now thinking that perhaps this patent was actually for the system of fret marking on a simple learning/teaching instrument...shown on the drawings. There are something similar to shape-note symbols inscribed on each fret- identifying the notes produced at various positions on the fretboard. A patent for a specific method of teaching/learning using such fret markers would be more easily patentable, and one could then more logically include the broader claim that it applies to whatever size/shape of the base instrument. Does the patent description mention this marking system?
