What are the main claims of U.S. Patent 11,884,634?
Claims Overview
The patent contains 15 claims, divided into independent and dependent categories.
Independent Claims
- Claim 1: A chemical compound with a specific molecular structure, characterized by substituents denoted as X, Y, Z, and R in a defined chemical scaffold. The claim includes salts and solvates of the compound.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 3: A method for treating a disease or condition associated with a biological target, involving administering an effective amount of the compound of claim 1.
Dependent Claims
- Claims specify various substitutions on the core scaffold, exclusive salt forms, and different formulations.
- Claims 10-15 specify particular dosing regimens, administration routes, and conditions (e.g., specific diseases like cancer or neurological disorders).
Chemical Structure Specifications
The claims describe a core chemical structure with variable substituents X, Y, Z, R, allowing broad coverage across chemical analogs within the specified scaffold. This structural flexibility expands the patent’s reach to compounds sharing core features but differing in substituents.
Methodology and Use Claims
The patent emphasizes methods of treating diseases by administering the claimed compounds. These include oral, intravenous, and localized delivery formats. Use claims also specify dosage ranges, generally between 1 mg and 1000 mg per day, depending on the condition.
