Given the utter crap that's been given patents combined with the mechanical complexity of a golf ball, from club strike to landing, how likely are existing golf ball patents to be really bogus claims and drawings of dimples?
In any given 2-3 year time span, there's like what, maybe a dozen professional golfers so skilled that they are able to hit the ball on a predictable basis? The remaining pros vary wildly and the amateurs are all over the map, so assessing the claims and technology of golf balls is pretty difficult.
And the amateurs will do/buy anything to improve their game. I do some work at a country club and the schlock on sale to golfers makes global warming skeptics look like Einstein.
And it also wouldn't surprise me if the markup on golf balls was stratospheric, representing the general affluence of many golfers, so there's lots of profit being protected here.
