The patent has a 20-year term from the filing date, extending to March 3, 2034, subject to maintenance fees.
What Are the Key Claims?
Core Claims Overview
| Claim Type |
Scope Summary |
| Compound Claims |
Defines specific chemical structures with variation in substituents and stereochemistry, e.g., Claim 1 covers compounds of formula [abbreviated formula], where R1, R2, R3 vary within defined groups. |
| Method of Use Claims |
Encompasses administering the compound for treating conditions linked to the targeted pathway, such as cancer or neurological disorders. Claim 10, for example, describes a method of treatment involving administering a therapeutically effective dose. |
| Composition Claims |
Covers pharmaceutical formulations containing the compound with carriers or diluents, such as Claim 15 describing a formulation containing 10-50 mg of the active compound. |
| Synthesis and Delivery Claims |
Detail processes for synthesizing the compound or delivering it in a controlled manner, including specific solvents, catalysts, or delivery devices. |
Notable Limitations and Variants
- Variants are limited to specific substituents that increase selectivity or bioavailability.
- Stereochemistry is explicitly claimed to optimize activity and reduce side effects.
- The claims specify dosing regimens (e.g., daily administration of 20 mg) to establish treatment protocols.
Exceptions and Exclusions
- Claims exclude compounds with certain substituents known for toxicity.
- Use claims do not extend to non-therapeutic applications.
