I wanted to get the opinions of players that are around good cues and bad cues and thier thoughts on patents and if there is any truth to it ...
The highlighted things above are not necessarily related. That is, I doubt that many (if any) pro or A+ players have relevant experience in patents - either getting them, asserting them, or defending against them.
However, many can speak to cue values independent of any patent value. Perhaps that is a better question to ask here on AZ. And actually, there are probably many threads on cue value here if you did a search.
In answer (generically) to your original question about patents though: a patent gives the patent owner the right to exclude others from practicing/making the invention in the patent. It does not give the patent owner the right to actually make the invention.
Also, each part of the pool cue could be patented independently. That is, there could be a patent on the butt cap, bumper, core, glue, bolts, wrap, forearm, points, inlays, joint, joint pin, shaft, ferrule, tip, etc. And the way the cue is made (the process of assembling) could also be patented. With this in mind, a cue may actually be subject to many patents in the same way a car is.
Typically, patent owners make make money by licensing their invention to others to make and sell. Or if there is a product that can be made by the patent owner without violating another patent with related technology, the patent owner could sell that product and excluding all others from making it during the life of the patent (which is (now) 20 years from filing).
Lastly, the value of the cue is still probably going to be dictated by the cue market. It could be protected by 100 patents, and it's still only worth what someone will pay for it.
