Where can terms used in Claims be defined according to lexicography rules?

The correct response highlights that terms used in claims can be defined in the specification and drawings filed with the application. This aligns with lexicographic practices in patent law, which allows for clarity and specificity in patent claims.

When defining terms within a patent application, the specification is the primary document that provides context. It is here that inventors explain their inventions in detail, offering definitions that can clarify how specific terms are used in the claims. The specification acts as the narrative voice of the application, setting forth the technical background and providing the context necessary to understand the meaning of the terms employed in the claims.

Drawings, when included, further support the definitions by visually illustrating aspects of the invention that may otherwise be difficult to convey through text alone. This visual representation can enhance understanding and function as an additional source of definitions.

In reference to the other potential responses, defining terms only within the claims would limit the ability to clarify terms properly, as the claims are often meant to claim the invention rather than serve as a dictionary. Defining terms in any document referenced in the application could lead to ambiguity, as not all referenced documents may have the same authoritative weight or clarity regarding definitions. Lastly, the assertion that terms cannot be defined in claims at all is incorrect
