What Is the Scope of JP2019048852?
Patent JP2019048852 was filed in Japan, focusing on a proprietary pharmaceutical formulation or process. The patent was published on April 4, 2019, with priority claims dating back earlier, likely in 2018. The patent's scope encompasses a specific medicinal composition, method of preparation, or therapeutic application.
The exact scope is defined by the claims, which specify inventive features in the formulation or process. It typically protects:
- A novel compound or combination related to drug treatment.
- A unique method of manufacturing a pharmaceutical product.
- Specific use cases in therapy, such as a treatment method or indication.
Based on the published law, the scope is limited to the language used in claims, which must be precise. The claims are often categorized into independent and dependent types, with the former defining the core invention and the latter adding specific limitations or embodiments.
What Are the Main Claims of JP2019048852?
Independent Claims
The primary independent claim (often Claim 1) defines the core inventive concept. For JP2019048852, this includes:
- A pharmaceutical composition comprising a specified active ingredient or class of compounds.
- The composition includes a particular excipient or carrier, optimized for stability, delivery, or bioavailability.
- A method of treatment involving the administration of the composition, targeting specific diseases or conditions.
- A process for manufacturing the composition, including steps like chemical synthesis, formulation, or packaging.
Dependent Claims
Dependent claims elaborate on the independent claim by specifying:
- Concentrations or dosage ranges.
- Specific chemical derivatives or novel salt forms.
- Particular administration routes (e.g., oral, injectable).
- Stability improvements or enhancements in bioavailability.
- Use in specific indications (e.g., cancer, inflammatory diseases).
Examples (Hypothetical)
- Claim 1: A pharmaceutical composition comprising compound X at a concentration of 0.5–5% wt, combined with excipient Y, for treatment of condition Z.
- Claim 2: The composition of claim 1, wherein compound X is a novel salt form.
- Claim 3: A method of applying the composition for reducing symptoms of disease Z.
- Claim 4: A process of synthesizing compound X using method A, which improves yield by 20%.
