Patent Overview: JP5534533
The patent encompasses a novel chemical compound or pharmaceutical composition, along with its therapeutic applications, primarily targeting a specific disease indication, likely involving metabolic pathways. The patent claims cover both the compound itself and its use in medical treatment, establishing broad legal protection.
Patent Family and Priority
- Priority dates often trace back to earlier applications filed in Japan or internationally under the Patent Cooperation Treaty (PCT).
- This patent may be part of a broader patent family, extending rights across major jurisdictions (e.g., US, EP, CN).
Scope of the Patent
Main Features
- Chemical Composition: The core of JP5534533 likely includes [specific chemical structure], possibly a small-molecule drug or biologic. Patents of this type generally focus on novel structures that demonstrate improved efficacy, safety, or pharmacokinetics.
- Therapeutic Use: The patent emphasizes the use of the compound in treating diseases, potentially related to metabolic syndromes, neurological disorders, or inflammatory conditions, depending on the法人's research focus.
- Formulation and Delivery: The patent may include specific formulations (e.g., sustained-release, injectable forms) or administration methods enhancing stability, bioavailability, or patient compliance.
Legal Scope & Breadth
The claims aim to protect novel compounds with defined structural features, along with their medical use. The breadth is typically structured around:
- Product claims: Covering the chemical compound(s) with specified structural features.
- Use claims: Describing use in treating particular diseases or conditions.
- Method claims: Encompassing methods of synthesis, formulation, or administration.
The scope thus seeks to balance broadening IP rights to cover potential variants, while maintaining novelty and inventive step.
Claims Analysis
