I want to know how I can find out if US6506148 is a real patent or a hoax?
This is currently my first attempt to answer my question. I have not looked or
searched anywhere else.
It is a real patent in that it has been granted. That does not guarantee that the invention actually works. There is no burden to prove that a patented technology works before having a patent granted. If it doesn't work, it isn't much value as no one would want to infringe the patent anyway. This doesn't mean the patent won't cause problems as prior art for other inventions. That said, an invention that doesn't actually work should not, in my opinion, be granted a patent as it doesn't demonstrate utility or enablement.
