Claims Analysis
Claim Structure
The patent includes multiple claims that define the scope of the invention. These claims are categorized into independent and dependent claims.
Independent Claims
Independent claims stand alone and do not refer to any other claims. They define the broadest scope of the invention. For example, Claim 1 might describe a deacetylase inhibitor compound with specific structural features.
Dependent Claims
Dependent claims refer back to and further limit the scope of an independent claim. These claims often describe specific embodiments or variations of the invention, such as particular methods of synthesis or application.
Claim Indefiniteness
Patent claims must provide reasonable certainty in defining what is patented, as mandated by 35 U.S.C. § 112. The claims in US6833384B2 must be precise enough to inform those skilled in the art about the scope of the invention with reasonable certainty, while recognizing that absolute precision is unattainable[2].
