 John traveled to my office and he couldn't make it any easier for us. It kind of took the fear out of spending money we didn't have at the time on the patent. He gave us confidence to move forward with the patent and he wrote a really strong patent. As a matter of fact, in 20 years, we've never had a product even come close to our product. That's how strong the patents are. We've watched other devices get copied, but because our patent was so strong, they can't do it.
