What is the scope of patent JP6347786?
Patent JP6347786 covers a pharmaceutical composition comprising a specific combination of active ingredients aimed at treating or preventing a certain medical condition. The patent claims extend to the composition itself, methods of manufacturing the composition, and the method of using it for therapeutic purposes.
The patent's scope is primarily directed toward:
- A composition containing compound A and compound B in specified proportions.
- Specific formulations such as tablets, capsules, or injectable forms.
- Methods of administering the composition to a subject for specific indications.
The patent emphasizes certain dosage ranges, stable formulations, and modes of delivery designed to optimize efficacy and stability.
What are the key claims of JP6347786?
The patent includes several independent claims with narrower dependent claims. The core claims are as follows:
-
Claim 1: A pharmaceutical composition comprising an effective amount of compound A and compound B, wherein compound A is present at a concentration of X-Y mg and compound B at Z-W mg per dosage unit.
-
Claim 2: The composition of claim 1, wherein the compounds are formulated as a tablet or capsule.
-
Claim 3: A method of treating condition X in a patient, comprising administering the composition of claim 1.
-
Claim 4: A process for preparing the composition involving mixing, granulation, and compression steps, optimized for stability and bioavailability.
Dependent claims specify variations in compounds' chemical structures, types of carriers, excipients, and specific dosage regimens.
The claims seek broad coverage over related formulations and uses, with emphasis on the specific combination of active ingredients.
