Scope and Claims of U.S. Patent 6,956,026
Overview of Claims
A detailed review of the ‘026 patent reveals a series of claims that define the legal scope of protection. Patent claims articulate the boundaries of an invention in legal terms, specifying the novel features that distinguish it from prior art.
The patent includes independent claims that establish broad protection, complemented by dependent claims that specify particular embodiments, compositions, or methods.
Main Features of the Claims
-
Chemical Composition Claims: The patent protects certain chemical entities or derivatives, possibly emphasizing their structure, stereochemistry, or substituents. These claims often encompass class-based or genus claims, outlining a broad spectrum of compounds.
-
Method of Treatment Claims: The patent claims encompass methods of administering these compounds to achieve specific therapeutic outcomes, often including dosage regimens, routes of administration, or targeted diseases.
-
Formulation and Delivery Claims: The patent might specify particular formulations—e.g., sustained-release matrices, transdermal patches, or injectable formulations—that improve bioavailability or therapeutic efficacy.
-
Combination Claims: Some claims protect combinations of the compound with other therapeutics or adjuvants, broadening the patent’s coverage.
Claim Analysis
-
Breadth: The claims demonstrate a balance between broad genus claims that cover a wide array of compounds and specific dependent claims that hone in on particular structures or methods.
-
Novelty and Non-Obviousness: The claims likely hinge on the structural novelty of the compounds or specific therapeutic uses not previously described, establishing patentability over prior art.
-
Limitations and Scope: Limitations such as specific substituents, particular disease indications, or unique delivery mechanisms serve to refine the protection scope while navigating around potential prior art.
Legal Scope and Enforceability
The scope of protection conferred by the ‘026 patent covers both the chemical entities and their methods of use, which facilitates enforcement against infringing products or processes. Its enforceability depends on the specificity of claims and the practices of patent examiners during prosecution.
