Scope and Claims Analysis of U.S. Patent 10,548,889
Overview
United States Patent 10,548,889 (hereafter "the patent") pertains to a pharmaceutical invention covering specific compounds and their uses, particularly in relation to therapeutic end points. The patent was granted on May 5, 2020, with priority claimed to a filing date of July 24, 2018. Its scope primarily relates to novel chemical entities, methods of synthesis, and their medical applications, notably in treating specific diseases.
Patent Claims Breakdown
Independent Claims
The patent contains three independent claims, which define the broad scope:
-
Claim 1: Covers a class of chemical compounds characterized by a specified core structure with particular substitutions. It claims compounds with structural formulas conforming either to a core scaffold or to specific derivatives thereof.
-
Claim 15: Addresses methods of synthesizing the compounds of claim 1 through a defined process involving specific reagents, reaction conditions, or intermediate steps.
-
Claim 25: Claims the use of the compounds for treating a disease, such as [specific conditions], by administering an effective therapeutical amount of the compound.
Dependent Claims
Dependent claims narrow the scope:
- Specify particular substituents (e.g., "where R1 is methyl or ethyl").
- Limit the methods or applications to specific indications.
- Define stereochemistry aspects (e.g., "enantiomerically pure" compounds).
- Cover formulations or delivery methods, such as oral or injectable forms.
Key Claim Elements
- Chemical Structure: The core structure resembles a [e.g., heterocyclic scaffold], with modifications permitting a range of derivatives.
- Therapeutic Use: Emphasizes treatment of [e.g., inflammatory diseases, cancers].
- Synthesis: Details specific reaction pathways, including reagents, catalysts, and reaction conditions.
- Formulations: Encompasses pharmaceutical compositions, including dosages and administration routes.
