I wonder, did anyone here take the time to read the actual patent? I did, and it makes all those who are claiming this patent to be vague look completely ignorant, which would be true of anyone who has not read the actual patent document. The document is very detailed and spells out exactly how the device works. I am not a fan of over-reaching patents but in my opinion (which I feel hold some merit as I am a private inventor and have been in the patent process for some time) this patent is legitimate. Anyone who thinks this patent is too vague would have to agree that Harley Davidson's patent on the V-Twin engine was way , way out of line too.
