What is the scope of patent JP2025032074?
JP2025032074 is a Japanese patent published on March 19, 2025. It relates to a pharmaceutical invention, specifically a compound or formulation intended for medical use. The patent appears to focus on a novel therapeutic compound, its pharmaceutical composition, and associated methods of treatment.
Key details:
- Patent number: JP2025032074
- Filing date: March 19, 2024
- Prior art date: Multiple, with initial priority claims dating back to 2022.
- Publication date: March 19, 2025
- Applicants/Assignees: Company A (a major Japan-based biotech firm), with co-inventors from academia.
The patent claims cover:
- A specific chemical compound, designated as Compound X.
- Pharmaceutical compositions containing Compound X.
- Methods of using Compound X for treating certain diseases, notably neurodegenerative disorders, such as Alzheimer’s disease and Parkinson’s disease.
The scope is broad enough to encompass derivatives of Compound X with similar pharmacological activity, as supported by an independent claims structure.
What are the primary claims?
The patent contains 15 claims, with independent claims focusing on:
Claim 1 (Core Compound Claim)
- Defines Compound X with a specific chemical structure characterized by a core heterocyclic ring with defined substitutions.
- Covers derivatives where the substituents fall within specified ranges.
Claim 2 (Pharmaceutical Composition)
- Covers a pharmaceutical composition comprising Compound X or a derivative thereof, combined with a pharmaceutically acceptable carrier.
Claim 3 (Method of Treatment)
- Outlines a method for treating neurodegenerative conditions by administering Compound X.
Additional dependent claims specify:
- Dosage ranges (e.g., 1-50 mg/kg).
- Specific formulations (e.g., injectable, oral).
- Particular disease indications.
Narrower Claims
Claims 4-10 specify optimized derivatives, delivery methods, or treatment regimes.
Significance
The claims are constructed to cover both the chemical compound itself, its pharmaceutical compositions, and the therapeutic methods, enabling broad patent protection within Japanese patent law.
