First let me congratulate you on getting a patent. Its a long process and can be expensive as well.
I would like to point out though that enforcement of your patent on other jump cues using phenolic tips/ferrules would seem to have problems with prior art. In patent law, if it can be demonstrated that your idea has been in use by others prior to your patent filing, then it presents real problems for you to enforce the patent and collect royalties. Prior art can invalidate a patent when a case gets to court, because the US Patent office has issued many patents that did not have the adequate due diligence done on prior art.
I clearly remember using jump cues with one piece tip/ferrules in the early 90s. In particular I owned one of those silver pipe cues that were pretty thick, like 16 or 17mm ferrule size that were all one piece phenolic.
I read over your patent and with no interest in this matter one way or the other, I find it difficult to understand which part of your invention is unique and with no prior use by others going back into the 90s. If I missed it and you have an idea incorporated into your jump cues that is completely novel and was not in use prior to your use, then yes by all rights you deserve to be recognized and financially rewarded for this.
I read it over and did not find any wording on special made materials. It just mentions a one piece ferrule/tip. Unless I missed something, this would be awfully hard to enforce to get royalties from other cue builders.
