Hello all...
I was approached by Mike G. from Baby's Pro Shop at a recent show... He more or less got in my face and demanded that I stop selling or building break cues with a one-piece ferrule design or face prosecution. His main claim was a recently filed patent, which he proceeded to waive in my face.
I was under the strong impression that a US patent does NOT apply if you can prove that you've been making the patented item PRIOR to the patent's filing date.
Have any of you ever run across this issue (or similar) before? Am I doing anything illegal?
