body: Are patents the only type of IP right that applies to physical, functional things, or can copyright and trademark also apply?
  
  
  For example, say a third party wants to manufacture and sell a purely functional part of a car, like part of the engine, not something like a badge or hood ornament that's likely trademarked. If the part is not covered by a patent, are they in the clear? Or could some other type of IP right apply to, say, a bolt hole pattern?
