Expiration Date: March 4, 2032, assuming no terminal disclaimers or extensions
Classification: The patent falls broadly under the Cooperative Patent Classification (CPC) codes related to pharmacology and drug delivery, such as A61K (Preparations for medical, dental, or toilet purposes) and C07D (Heterocyclic compounds).
Scope of the Patent
Technical Field
The patent addresses methods and compositions involved in the treatment of specific diseases or conditions, leveraging novel compounds or combinations. It potentially covers:
- Novel chemical entities with therapeutic activity.
- Specific formulation strategies.
- Targeted delivery mechanisms enhancing drug efficacy or reducing side effects.
- Use of compounds for particular indications.
Core Focus
The core inventive concept involves the use of a specific compound or combination thereof that demonstrates a superior therapeutic profile against a particular disease or condition. The scope extends to:
- Administration methods (oral, injectable, topical).
- Dosage regimens.
- Co-administration with other agents.
The patent aims to protect both the compound itself and the methods of use, including any unique delivery technology or formulation.
Claims Analysis
The patent's claims define the legal scope of protection. They are divided into independent and dependent claims.
Independent Claims
-
Claim 1: Typically, a broad claim covering the compound or composition with specific structural features or a combination for use in a particular therapeutic method. For example:
"A pharmaceutical composition comprising Compound A, or a pharmaceutically acceptable salt thereof, for use in the treatment of Disease B."
-
Claim 10 (or similar): Usually, a method claim covering the method of administering or treating the disease with the compound.
Dependent Claims
- Narrower claims adding specifics such as concentration ranges, dosage forms, additional therapeutic agents, or specific chemical derivatives.
Claim Construction
The claims employ Markush formats, encompassing various derivatives, salts, or analogs, broadening the scope while maintaining focus on the core compound or method.
Strengths and Vulnerabilities
- Strengths: The independent claims are sufficiently broad to cover multiple embodiments, which enhances enforceability. Claims may also include both composition and method claims, providing comprehensive protection.
- Vulnerabilities: Overly broad claims risk invalidation if prior art discloses similar compounds or methods. Narrow claims targeting specific derivatives can help mitigate this risk.
