These are broad and set the foundation of the patent. JP6039152 possibly includes independent claims claiming:
- A specific pharmaceutical composition comprising X active ingredient, possibly in a unique formulation or with an innovative excipient.
- A method of treating Y disease using a particular compound or combination thereof.
- A novel formulation method that enhances drug stability or absorption.
-
Dependent Claims:
These narrow the scope, adding specific details such as:
- Concentration ranges of active ingredients.
- Specific excipients or carriers used.
- Administration routes or dosing regimens.
- Particular chemical derivatives or crystalline forms.
3. Specific Claim Highlights
(Hypothetical Example Based on Common Patent Claims):
- Claim 1: A pharmaceutical composition comprising [X] at a concentration of [Y] mg, formulated in [specific form].
- Claim 2: The composition of claim 1, wherein [X] is a crystalline form with improved stability.
- Claim 3: A method for treating [disease], comprising administering the composition of claim 1 to a subject in need thereof.
4. Claim Interpretation and Novelty
The scope indicates focus on:
- Novel active ingredient configurations or formulations not previously disclosed.
- Specific combinations or delivery methods that result in improved therapeutic outcomes.
- Unique chemical crystalline forms or polymorphs.
Japanese patent law emphasizes novelty, inventive step, and industrial applicability, and claims are structured to maximize these aspects, while remaining clear and unequivocal.
