What does 35 U.S.C. § 112(b) stipulate regarding the specification?

35 U.S.C. § 112(b) emphasizes that the specification must include clear and definite claims that distinctly claim the subject matter which the applicant regards as their invention. This requirement is crucial because it serves to notify the public of the boundaries of the patent protection sought. The clarity and definiteness of claims are vital to ensure that others can understand what the patent protects and how it relates to existing technologies. This prevents ambiguity and potential disputes over the scope of the patent.

While a summary of the invention and clarity in the language used are important components of the specification, they do not carry the same weight in terms of legal requirement as the clear claims do. Claims are the defining elements that delineate the inventor's rights, making option B the essential focus of § 112(b). Moreover, vagueness is not permissible under this statute; the specification and claims must be sufficiently detailed to inform a person skilled in the art about the invention.
