Notes:
According to Wikipedia: "Gebrauchsmuster (GebrM), also known as German utility model ..., is a patent-like, intellectual property right protecting inventions. The Gebrauchsmuster is slightly different from the patent. It mainly differs from the patent in that processes and methods cannot be protected by a Gebrauchsmuster, only products can."
