 Shoe Patent

Now I had patented that design, but first thing I knew everyone started to copy it. All Manufacturers. But we did a lot with it. You had to sue them and we didn’t have that much money. We were a small company, see? Cost you and dragged on for 2 or 3 years. By the time the trial comes up the style is all gone, over. Wasn’t worth it. After a while I stopped patenting styles. It didn’t pay.   – Ben Benjamin
