It baffles me as to which GT40 shape you could trademark. There were so many. I would venture a guess, that the GT40 falls into a generic mid-engine configuration /shape. I was involved in a law suit in the '70's where I was sued for using a person's car shape in my business logo. The shape I used was a "head on shot" of the 917 Porsche. The person's car was a B16 Chevron Coupe. I showed the court pictures of every mid engine race car I could find. The court said that they all looked pretty much the same, so it must be a generic shape and configuration. The court saw in my favor. What got me, is I sold the guy the Chevron!
