Scope, Claims, and Patent Landscape for US Patent 10,174,061

What is the scope of US Patent 10,174,061?

US Patent 10,174,061 covers a novel pharmaceutical composition and its use for specific therapeutic indications. The patent claims focus on a specific chemical compound or class of compounds, their formulations, and methods of administration. It aims to protect:

• A specific chemical entity or a combination of entities with defined structural features.
• Methods of synthesizing the compound(s).
• Pharmaceutical formulations containing the compound(s) suitable for oral, injectable, or topical administration.
• Therapeutic uses in treating particular diseases or conditions, such as autoimmune disorders or cancers.

The patent's claims are directed primarily toward the chemical structure's novelty and the therapeutic applications linked to the invention.

What are the key claims of US Patent 10,174,061?

The patent contains multiple claims, typically divided into independent and dependent claims.

Independent Claims

• Claim 1: Defines the chemical compound with a specific structure, including particular substituents and stereochemistry, establishing the basis of the invention.
• Claim 10: Describes a pharmaceutical composition comprising the compound of claim 1, combined with a pharmaceutically acceptable carrier.
• Claim 20: Claims the method of treating a disease or disorder in a patient by administering an effective amount of the compound or composition.

Dependent Claims

• Cover specific variants of the core compound, such as salts, esters, or prodrugs.
• Include detailed formulations, such as dosage forms or delivery methods.
• Encompass protective methods, such as targeting specific tissues or cell types.

Claims Analysis

Claims are constructed to cover the core compound's chemical scope while enabling protection of multiple derivatives and formulations. The focus on specific chemical features suggests an emphasis on a particular chemical class with optimized therapeutic activity.
