This is unrelated to the question I have posted under Trademarks.
Again, a fictious analogy.
Man A invents a new ukulele neck, that is stronger, lighter, and much cheaper to manufacture than prior ukulele necks. He definitely wants to obtain a utility patent, and dreams of retiring in Hawaii, lying under a palm tree, while being serenaded by women playing ukuleles of his design.
His ukulele neck design is also visibly unique....visibly quite different than all prior ukulele necks. It would be practically impossible to make a ukulele neck that looks like his ukulele neck, without also violating the core of his invention, as would be explained in a utility patent application.
Given the uncertainty of obtaining a utility patent, is the man well advised to file for both a utility patent and a design patent...in case the utility patent somehow is not granted? If the man wishes to file both, is it wiser to file the utility patent first, or the design patent first, or both at the same time?
If the man is poor, and cannot afford a patent lawyer, is he well advised to try to obtain the simpler design patent, or to try to get the utility patent on his own?
