What is required to use the UDH?
A license. The bike brand needs to sign up for a free license. The license gives the licensee the right to use the UDH patent and the UDH trademark. A bike brand may want to make their own slightly different derailleur hanger with different features. This is ok. However in order to mark their frames with the UDH trademark they must conform to UDH frame and hanger specification. This ensures that if a rider breaks their hanger, it can still be replaced with a standard UDH hanger.
