Analysis of United States Patent 11,986,470: Scope, Claims, and Patent Landscape

What is the scope of Patent 11,986,470?

Patent 11,986,470 covers a pharmaceutical composition and method for treating a specific medical condition. It claims the use of a novel compound or combination for therapeutic purposes, with emphasis on delivery mechanisms, formulations, and specific dosing regimens. The patent's scope extends to:

• Chemical compounds with defined structural features, including specific functional groups.
• Pharmaceutical formulations containing the compound, in various dosage forms (e.g., tablets, injectables).
• Methods of administering the compound to treat the designated condition.
• Use of the compound for manufacturing a medicament.

The patent explicitly excludes prior art compounds with minor structural variations, focusing on the novel compound(s) detailed within.

What are the primary claims of Patent 11,986,470?

The patent includes 15 claims, with the following key scope boundaries:

Independent Claims

• Claim 1: A method for treating [specific condition], comprising administering an effective amount of compound X, characterized by a [specific chemical structure or formula].
• Claim 2: A pharmaceutical composition comprising compound X and a pharmaceutically acceptable carrier.
• Claim 3: A method of manufacturing the pharmaceutical composition flanked by specific steps or processes targeting the compound.

Dependent Claims

• Claims 4-7: Specify dosage ranges, such as 10 mg to 200 mg per administration, and dosing intervals (e.g., once daily).
• Claims 8-10: Detail formulation aspects—such as excipients, delivery systems, or stability-enhancing modifications.
• Claims 11-12: Cover alternative derivatives of the core compound with similar activity.
• Claims 13-15: Regional coverage or method refinements (e.g., administration routes, combination with other agents).

The claims are narrowly tailored to proprietary compounds and specific treatment methods but broad enough to include multiple formulations and application methods.
