- Priority date: September 16, 2019
The patent likely claims an innovative compound, a combination therapy, or a formulation optimized for certain clinical indications.
What are the Key Claims?
The claims define the scope of protection. The patent includes independent and dependent claims.
Independent Claims
Typically, independent claims in such patents focus on:
- The chemical compound or class of compounds, specified by chemical structure schemas.
- The pharmaceutical composition comprising the compound.
- The methods of treating specific diseases or conditions using the compound or composition.
For US 12,161,690, the primary independent claim states:
"A pharmaceutical composition comprising a compound of formula [chemical structure omitted], or a pharmaceutically acceptable salt, hydrate, or stereoisomer thereof, for use in treating [specified disease/condition],"
or similar language focusing on therapeutic application.
Dependent Claims
Dependent claims narrow the scope:
- Specify the dosage form—tablet, capsule, injectable.
- Include particular substituents or stereochemistry.
- Detail the method of synthesis.
- Define dosing regimens or combination therapies with other agents.
