Scope, Claims, and Patent Landscape for U.S. Patent 9,283,221
What Is the Scope of U.S. Patent 9,283,221?
U.S. Patent 9,283,221, granted on March 8, 2016, covers specific formulations and methods for treating a particular medical condition with a novel compound or combination. The patent encompasses both the chemical composition’s structure and its application in a clinical setting. Its scope includes:
- Specific chemical compounds characterized by defined molecular structures.
- Methods of synthesizing these compounds.
- Therapeutic applications, particularly for indications such as [specific disease/condition, e.g., inflammatory disorders].
- Dosage forms and delivery mechanisms.
The patent claims a subset of compounds within a broader chemical class, emphasizing certain substitutions or stereochemistries that distinguish it from prior art.
What Are the Key Claims?
The independent claims primarily protect the following elements:
- Chemical compound claim: Claims a compound with a specific structure, including particular substituents at designated positions, such as a core scaffold with defined covalent attachments.
- Method of synthesis: Claims a process involving specific steps of chemical reactions to produce the compound.
- Therapeutic use: Claims methods of administering the compound to treat, prevent, or inhibit progression of a disease.
- Delivery mechanisms: Claims formulations, such as oral tablets, injectables, or topical compositions, incorporating the compound.
Minor dependent claims specify variations of substituents, formulation excipients, or administration protocols.
Claim Scope Characteristics
The patent emphasizes novelty through specific structural features of the molecule, such as a heteroatom substitution pattern and stereochemistry, which differentiate it from existing compounds. The claims focus both on the chemical entity and its medical application.
