Claims Analysis
1. Independent Claims:
The independent claims outline the broadest legal protection, delineating the fundamental inventive concept. In JP2014221845, the core claim likely covers:
- A process involving specific steps—e.g., mixing particular ingredients in a specified order, under controlled conditions (temperature, humidity, pH).
- Use of unique intermediates or stable forms of a pharmaceutical compound.
- Particular physical states or particle sizes achieved via the process, contributing to improved drug properties (e.g., dissolution rate).
2. Dependent Claims:
Dependent claims add specific limitations to the independent claims, narrowing the scope but reinforcing patent strength. They may specify:
- The type of excipients or stabilizer used.
- Precise temperature ranges.
- Specific equipment configurations.
- Additional process steps that enhance the core method.
3. Claim Language and Interpretation:
The language of the claims is precise. For example:
- Terms like “comprising” denote open-ended inclusion.
- Phrases such as “wherein the step involves...” specify added features providing protection for particular embodiments.
Legal Foresight:
- Given the broad wording, the patent offers substantial protection for the disclosed manufacturing method.
- However, some claims may be challenged if prior art demonstrates similar processes, especially if the claimed steps are conventional.
