It's not clear to me how far can you move when you are making replica of something. On this example can you help me understand it better please?
Let's say I would like to build the replica of the engine and sell it. It will be not working, just standing on the display. So in general - it will have shape, but not function of the original product.
I know that I can not put any trademark on it. I know as well that it can not work, as it would be against patents. Would it be still legal to make one?
What if my engine will have same moving parts as the original one, but still will be not able to work. If those moving parts are part of claims in the patent to use in engine patent, will it be illegal to mimic them in replica?
