If a name or denomination is contrary to public order or morality due to the nature of such name or denomination or due to the use of such name or denomination, especially if the use of such trade name for a business may constitute misleading in the course of trade or the public, such name or denomination shall not be used as a trade name. If a Mark that is identical or similar to a trade name is used as another trade name or Mark, without any necessary approval, and thus misleads the public, such trade name shall be protected
