What Are Multiple Dependent Patent Claims and Their Legal Implications?

Definition & Meaning

Multiple dependent patent claims are a type of patent claim that refers to more than one other claim within a patent. In simpler terms, a dependent claim is one that relies on another claim for its validity, while a multiple dependent claim can refer to several claims at once. This structure can create confusion, especially concerning the calculation of fees associated with filing these claims. Due to this complexity, multiple dependent claims are often viewed as poor practice in the United States patent system.
