Can I make an atom for atom reproduction of 1980 Porsche 911 and sell it on the open market (removing the name of course)?
Regardless, it could be a good idea to offer this service to the original patent holder. It would offer them a chance to recover sunken costs.
Which makes it sound like making exact reproductions is completely legal. Which is exactly what I would think.
If you patent a drug, there is no other representation of thing. A molecule is a molecule.
Although I do see a tricky subversion of patent law where one would attempt to get copyright woven intricately into the fabric of the invention to get 70 years past the death of the artist (corporation).
hypothetical: "I am sorry that was not a novel single cycle divider circuit that exact representation of gates is a new Piet Mondrian!"
