Understanding the Declaration of Invalidity in Legal Contexts

Definition & Meaning

A declaration of invalidity is a legal ruling that renders a previously registered patent, trademark, or marriage void. In the context of patent and trademark law in the United Kingdom, it allows individuals to challenge the validity of a registered mark. In family law, it serves to annul a marriage, indicating that it did not meet the necessary legal requirements for a valid union.
