Scope and Claims
Claim Structure and Types
Taiwan patents, like others, typically feature independent and dependent claims:
- Independent Claims: Define the core invention broadly and set the scope.
- Dependent Claims: Narrow the scope, specify particular embodiments, or add features.
Claim Analysis:
-
Scope of the Core Invention
The primary independent claim likely encompasses a novel pharmaceutical composition or method involving a specific API, its derivatives, or formulations. For example, claims may describe a particular combination, excipient, or delivery system that enhances bioavailability or stability.
-
Scope of Use
Secondary claims may specify therapeutic indications, such as treatment of particular diseases, expanding the patent’s commercial reach.
-
Manufacturing Methods
Claims may detail manufacturing steps or processes that improve efficiency, purity, or yield, thereby providing process protection.
Claim Language and Limitations
- Broadness: The claims appear designed to cover both the chemical entity and its derivatives, creating a robust shield against competitors.
- Specificity: Details like dosage forms, manufacturing parameters, or specific chemical structures bolster enforceability.
- Potential Overbreadth: Excessively broad claims might face validity challenges if prior art exists. The claims likely balance breadth with novelty and inventive step.
