They Don't but if you think anyone wants to go through what Kent Ritter went through you are crazy. Their are laws and you just cant copy a patent ya know ? Liscensing etc etc. This has happened before hence why Kent did what he did for the market.
I find it hard to believe that every aftermarket block, head etc... made by a third party, for any brand, is violating a patent. If that was the case, alot of people are breaking the law. Maybe they may pay a licencing fee if they mention the original Company name in their part description. But other than that..... I guess I need to find out, as I developed a Camshaft Belt Drive for the Gen 3 Hemi, that I'm real close to putting on the market.
