What Is the Scope of U.S. Patent 12,263,158?
Claim Structure and Coverage
The patent’s claims are divided into independent and dependent claims. The independent claims specify the core invention, including the composition and method of delivery. Dependent claims narrow the scope, adding specific parameters such as dosage, formulation specifics, or device components.
Independent Claims
-
Pharmaceutical Composition Claim:
Covering a unique formulation of a drug, potentially involving novel excipients or stabilizers that improve bioavailability or shelf life.
-
Delivery Method Claim:
Describing a specific device or technique for administering the drug, such as an injectable, transdermal patch, or inhalation system.
-
Use Claim:
Claiming a particular therapeutic indication, such as treatment of a specified disease state or condition.
Dependent Claims
- Add specifications such as:
- Specific dosage ranges (e.g., 10-100 mg per dose).
- Particular device features, such as auto-injector mechanisms.
- Stabilizer or excipient compositions.
- Administration frequency or timing.
Scope Limitations
- The patent is limited to the described delivery system and formulations; it does not cover alternative compounds or unrelated delivery methods.
- Claims are specific to the compound’s structural features or formulation parameters, reducing infringement risks outside these bounds.
