The Fifth Amendment of the U.S. Constitution guarantees, inter alia, that no person shall be deprived of property (including intellectual property), without due process of law. For instance, it is settled law that a federal statute may be so arbitrary and capricious as to violate due process. Similarly, it is settled that an administrative agency, e.g., the U.S. Patent and Trademark Office (USPTO), cannot escape the due process of law requirement when processing patent applications. In theory (less in reality), due process of the law extends to judicial as well as political branches of government, and judgments that violate constitutional limitations and guarantees are void or voidable.
