Scope and Claims Analysis of U.S. Patent 11,166,963
What Are the Core Claims and Scope of U.S. Patent 11,166,963?
U.S. Patent 11,166,963 covers a novel pharmaceutical composition targeting specific metabolic pathways. Its claims primarily encompass a chemically defined class of compounds with known therapeutic activity, methods of manufacturing these compounds, and their use in treating certain medical conditions.
Main Claims Breakdown
| Claim Type |
Details |
| Composition of Matter |
Defines a specific chemical structure, including substituent groups and stereochemistry, intended for drug development. |
| Method of Manufacturing |
Details synthetic routes, reagents, and conditions for producing the compounds. |
| Therapeutic Use |
Claims methods for treating diseases characterized by particular biological markers, such as inflammatory or metabolic disorders. |
The core claims include structural formulas and specific chemical variations that qualify as novel. Claims avoid broad genus coverage, focusing instead on narrow subclasses with particular substitutions.
Structural Scope
The patent discloses a chemical scaffold with variations at key positions. The scope includes compounds with modifications that retain activity, such as methyl, ethyl, and specific halogen substitutions at predetermined sites.
For instance, the patent emphasizes compounds with a heterocyclic core linked to a variable aromatic group, designed for improved bioavailability and target specificity.
How Does the Patent Define Its Claims?
Claim Construction
- Independent Claims: Cover the chemical core with specific substituents and stereochemistry. Example: "A compound comprising a heterocyclic ring attached to a phenyl group with substitution at position X."
- Dependent Claims: Narrow variations, such as specific substitutions at certain positions, stereoisomers, or formulations optimized for delivery.
Scope Limitations
The patent explicitly excludes compounds with structural modifications outside the defined chemical space. Claims focus on compounds demonstrated to have activity in specific assays, limiting broad interpretation.
