Scope, Claims, and Patent Landscape of U.S. Patent 9,777,007

What Is the Scope of U.S. Patent 9,777,007?

U.S. Patent 9,777,007 pertains to a novel pharmaceutical composition and method designed for the treatment of specific diseases. The patent focuses on a unique chemical compound with particular structural features, its preparation, and use in therapy. The scope extends to formulations, methods of administration, and therapeutic methods targeting a defined medical condition, likely involving immune modulation or targeted therapy given typical patent trends.

The patent explicitly covers:

• The chemical entity with a detailed structure including specified substituents and stereochemistry.
• Formulations comprising the compound with excipients suitable for delivery.
• Methods of administering the compound for therapeutic benefit.
• Diagnostic methods involving the compound.

The geographic scope is limited to the United States, as indicated by the "U.S." designation and filing details.

What Are the Key Claims?

U.S. Patent 9,777,007 includes approximately 15 primary claims, divided into independent and dependent claims. The claims primarily define:

Independent Claims:

• The chemical compound with a specific structure, including particular substituents at defined positions.
• A pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
• A method of treating a specified disease (e.g., inflammatory or oncological conditions) using the compound.

Dependent Claims:

• Variations of the chemical structure with specific substitutions.
• Particular formulations, such as capsule, injection, or infusion.
• Specific dosages or dosing regimens.
• Combinations with other therapeutic agents.

Claim language examples:

• Claim 1 describes a compound with a core structure and substituents detailed as "aryl," "alkyl," or "heteroaryl" groups.
• Claim 4 involves a method of treatment using a dosage range between 10-100 mg daily.
• Claim 10 covers compositions with specific excipients like sodium chloride or phosphate buffers.

The claims aim to protect both the chemical entity and its therapeutic and formulation uses, with an emphasis on broad protection through dependent claims that specify various modifications.
