I'm no attorney, Steve, but I used to own a plastic manufacturing plant. We were making a line of catering products for a company. They had registered their name and done everything prim and proper. We had been making the products for them for about a year and a half when they received a "Cease and desist" letter over their choice of name from an attorney, along with a threat to bring suit if they didn't. His attorney told him the Cease and Desist letter was more than likely a bluff................but if he refused it could be VERY expensive. There was no discussion. He ordered us to re-tool and change the name immediately. If I were in your shoes, I'd spend a little money to protect my forges name. Hiring an attorney to write a letter doesn't cost a lot of bucks. Losing your name and reputation will cost a whole lot of bucks. I'd bite the bullet and do it.
