Patent Overview and Abstract
JP2012087149 describes a novel method for producing a pharmaceutical composition, particularly emphasizing improved processing techniques that enhance stability, bioavailability, or efficacy of active pharmaceutical ingredients (APIs). While the abstract's exact wording is proprietary, it emphasizes methods relating to specific formulations, controlled processing conditions, and intermediate compounds.
Scope of the Patent
1. Technical Field:
The patent primarily pertains to pharmaceutical production methods, focusing on the preparation of drug compositions, especially solid dosage forms such as tablets, capsules, or powders.
2. Purpose of the Invention:
The invention aims to improve the manufacture process of pharmaceuticals to obtain superior stability, dissolution profile, or manufacturing efficiency, potentially addressing issues like moisture sensitivity, bioavailability challenges, or process reproducibility.
3. Core Innovations:
- Specific processing steps involving controlled temperature, humidity, or milling conditions.
- Use of particular excipients or stabilizers in conjunction with APIs.
- Novel intermediate compounds enabling easier or more effective final formulation production.
Claims Analysis
Understanding the patent’s claims is essential because they define the scope of exclusivity. JP2012087149 contains a set of claims that range from broad to more specific.
1. Independent Claims:
The primary claims establish the core novelty—generally, a method involving specific steps or composition features. For instance, an independent claim might specify:
- A process comprising mixing specific API with particular excipients under defined conditions (temperature, humidity).
- Utilizing particular intermediates that facilitate stable or bioavailable final forms.
- A step involving a unique drying or granulation technique.
2. Dependent Claims:
These specify particular embodiments, variations, or preferred embodiments resulting from the independent claims. Examples include:
- Specific ranges of temperature or humidity used during processing.
- Use of certain surfactants or stabilizers.
- Application to specific APIs, possibly indicating usages for compounds such as antihypertensives or anticancer agents.
3. Claim Scope and Breadth:
The claims are likely crafted to balance broad coverage—encompassing general process features—and specificity—restrictions to particular compounds or conditions. Such features minimize the risk of design-around strategies by competitors while providing patent enforceability.
