What is the Patent's Scope?
Taiwan Patent TW201118086 pertains to a pharmaceutical composition or method involving a specific drug formulation. It primarily covers formulations, their production processes, and potential therapeutic applications. The patent offers protection over particular combinations or methods designed to improve drug efficacy or stability.
What Are the Main Claims of TW201118086?
The patent comprises multiple claims, which can be summarized as follows:
Independent Claims:
- The composition of a drug with specified active ingredients, including concentration ranges.
- A method of manufacturing the pharmaceutical composition through a particular process, such as mixing, granulation, or encapsulation.
- Use of the composition for treating specific medical conditions, potentially including indications like cardiovascular or neurodegenerative diseases.
Dependent Claims:
- Variations in ingredient ratios.
- Specific excipients or carriers used within the formulation.
- Temperatures, pressures, or process conditions applied during manufacturing.
- Formulations in specific dosage forms (e.g., tablets, capsules).
How Broad Are the Claims?
The claims primarily focus on specific combinations of active ingredients and their manufacturing process. The scope is moderate; they cover certain formulations but do not broadly claim all possible combinations or uses of the drug. The patent may protect particular chemical entities and their combinations, preventing competitors from making identical formulations but leaving room for alternative formulations that do not infringe on the claims.
