where can i check on this patent?

But if this was the case how can golf companies, tennis companies and probably other sports have demo days where I can go in and try clubs from Ping or try raquets by Wilson but I can also go another day and try Nike clubs or head raquets it really doesnt make sense that bowling is the ONLY sport where its limited to one company supposedly also didnt track not long ago have a demo day and if so wouldnt this technically be infringing on the patent if such patent is actually enforcable and lastly can you really patent this as I thought a patent was for a product of sorts not an idea of advertising which once again would lead to commercials and many other advertising methods come into play which would be considered infringment. last and probably most obvious would be those test drive days or whatever they are called. Like Jeep has where you can try out all the jeeps on their course however if I remeber correctly there was a few other companies that do the same deal and in theorie this seems to be the same idea. lastly I could see the thumb being patented and in that thumb not being allowed for use without consent I think it is simply ebonite going off to scare Big B into not doing it and trying to reduce the competition "I can show my product and such but you cant" sort of idea and with as corrupt as our legal system is I dont blame Big B for not fighting it face it I could break in your house get hurt and sue you and win what kind of legal system is that.
