The scope can be summarized as covering novel derivatives or combinations of known drugs that demonstrate an unexpected therapeutic advantage for targeted disease states.
What are the key claims within U.S. Patent 11,395,889?
The patent contains multiple claims, typically divided into independent and dependent claims. The central claims focus on:
Independent Claims
-
Compound Claim: Defines a chemical compound with specific structural features, such as a core heterocyclic scaffold, substitution patterns, and functional groups.
Example: A compound comprising a core structure (e.g., quinazoline), attached with specified side chains and substitutions, which confer activity against a particular enzyme or receptor.
-
Method of Use: Claims the use of the compound or composition in preventing or treating specific diseases, like solid tumors or viral infections.
Dependent Claims
-
Variations of the compound: Include specific substitutions, such as methyl, halogen, or hydroxyl groups, on certain positions.
-
Formulations: Cover pharmaceutical compositions with the compound, including various excipients and delivery vehicles.
-
Methods of synthesis: Describe particular synthetic routes to prepare the claimed compounds, emphasizing efficiency or purity.
Claim Coverage and Breadth
The claims demonstrate a limited but focused scope, targeting specific chemical variants while excluding broad classes of unrelated molecules. The claims' breadth supports exclusivity over derivatives sharing similar core structures with certain permitted substitutions.
