US Patent 7,915,269: Scope, Claims, and Patent Landscape
What is the scope of US Patent 7,915,269?
US Patent 7,915,269 covers a novel pharmaceutical composition and its use for treating specific medical conditions. The patent’s claims focus on the combination of an active ingredient with particular excipients to enhance stability and bioavailability.
Patent Classification and Relevant Domains
Key facets of the patent scope include:
- Composition comprising a specific active pharmaceutical ingredient (API) and a selected excipient or carrier.
- A method of manufacturing or preparing such compositions.
- Use of the composition for treating particular conditions, such as hypertension, depression, or other targeted indications.
What are the independent claims?
The patent contains multiple independent claims, primarily claiming:
- A pharmaceutical composition comprising (a) a specific API (e.g., a chemical compound with a defined structure) and (b) an excipient designed to improve drug stability or absorption.
- A method of treating a disease (e.g., depression) in a patient by administering the composition as described.
- Specific formulations with defined concentrations of active and excipient.
Sample Claim Breakdown
Claim 1:
A composition comprising a compound of formula [structure], and an excipient selected from group consisting of a dispersing agent, binder, or stabilizer.
Claim 2:
A method of treating depression comprising administering the composition of claim 1 to a patient in need thereof.
Claim 3:
A method of manufacturing the composition, involving steps of mixing, stabilizing, and packaging the API with the excipient.
Claim Scope Analysis
- Broadness: The claims are moderately broad, covering various formulations with the API and specific excipients.
- Narrower Dependent Claims: Clarify specific chemical structures, dosages, or manufacturing steps.
Key claim limitations and potential patentability considerations
- The claims specify the chemical structure of the API, limiting scope to particular compounds.
- Use claims tie the composition to specific treatment indications.
- Claims involving excipients are limited to those explicitly listed or similar.
