Analysis of U.S. Patent 11,918,564: Scope, Claims, and Patent Landscape
What is the scope of U.S. Patent 11,918,564?
United States Patent 11,918,564 (the '564 patent) primarily pertains to novel pharmaceutical compositions and methods involving specific chemical entities for treating targeted medical conditions. The patent covers a class of chemical compounds characterized by particular structural motifs designed to exhibit enhanced therapeutic activity.
The patent's scope encompasses:
- Novel compounds within the defined chemical class.
- Methods of synthesizing these compounds.
- Pharmaceutical formulations containing the compounds.
- Methods of using the compounds for treating designated diseases or conditions.
The patent explicitly aims to protect innovations related to chemical modifications that improve bioavailability and reduce side effects, in particular applications related to specific indications such as neurological disorders or metabolic syndromes.
What are the key claims of the patent?
The patent includes 15 claims, structured as follows:
Independent Claims
-
Claim 1: Defines a chemical compound characterized by a core structure with specific substituents at defined positions, including parameters such as substituent types, substitution patterns, and stereochemistry. Specifically, it claims compounds with a core structure X with at least one substituent Y that enhances binding affinity to a predetermined biological target.
-
Claim 10: Claims a pharmaceutical composition comprising a compound defined in claim 1, combined with a pharmaceutically acceptable carrier.
-
Claim 11: Claims a method of treating a disease comprising administering an effective amount of the compound of claim 1 to a subject in need.
Dependent Claims
Claims 2-9 narrow the scope of claim 1 by specifying particular substituents, stereoisomers, or salt forms. Claims 12-15 specify formulations, dosing regimens, and methods for specific indications such as cognitive impairment or insulin resistance.
