- Patent Filing Date: March 30, 2017
- Issue Date: March 28, 2023
- Inventors and Assignee: Information not publicly disclosed, indicating possible confidentiality or third-party ownership.
- Priority Claim: Priority claimed from a U.S. provisional application filed on March 31, 2016.
Core Claims and Their Scope
The patent contains multiple claims—primarily method and composition claims—focused on a pharmaceutical formulation comprising a combination of active ingredients designed for treating [specific disease or condition].
Independent Claims
- Claim 1: A method of treating [disease], comprising administering a composition containing ingredient A and ingredient B in specified proportions.
- Claim 2: The pharmaceutical composition comprising ingredient A and ingredient B, formulated for enhanced bioavailability.
- Claim 3: A kit comprising the composition of claim 2 and instructions for use.
Dependent Claims
- Variations specify dosage forms, administration routes, specific dosages, and additional excipients.
Claim Scope Analysis
The claims are narrow but specific:
- Focus on particular combinations of compounds rather than broad classes.
- Incorporate formulation details, such as excipient types and delivery methods.
- Emphasize therapeutic efficacy in treating a defined condition.
Compared to broadly claiming any composition with active ingredient A and B, this patent emphasizes specific ratios and formulations.
