Filed on behalf of the applicant (assumed to be a pharmaceutical entity), JP2019504052 was published in 2019, reflecting recent advances in drug development. Although the full patent text is necessary for granular detail, typical patent claims in this context revolve around novel drug compounds, formulations, or therapeutic methods linked to a specific disease target.
Scope of the Patent
Technological Field
JP2019504052 appears within the domain of pharmacology, specifically targeting novel chemical entities or formulations designed for therapeutic intervention—possibly in oncology, neurology, or infectious diseases, as inferred from recent trends among similar patents.
Core Technical Focus
The patent's scope encompasses:
- Novel Chemical Entities or Derivatives: Structural modifications to existing drug molecules to improve efficacy, stability, or bioavailability.
- Pharmaceutical Compositions: Specific formulations, such as controlled-release matrices or co-crystals, designed to optimize pharmacokinetics.
- Therapeutic Methods: Use of the claimed compounds/methods for treating particular diseases or conditions, aligned with Japan’s regulatory framework.
Legal Scope and Claim Structure
Patent scope is primarily defined through independent claims, which articulate broad inventive concepts, and dependent claims, which refine or specify particular embodiments.
- Independent Claims: Likely encompass the chemical structure of novel compounds, their salts, or polymorphs with potential pharmaceutical utility.
- Dependent Claims: May specify particular substituents, methods of synthesis, dosage forms, or methods of use—e.g., treatment of specific cancers or neurological disorders.
The scope aims to establish a hierarchy of rights, shielding broad classes of compounds and their uses, thereby deterring generic or reverse-engineered counterparts.
Key Claims Analysis
Claim Type and Breadth
Published patents in this field often include:
- Chemical Composition Claims: Covering the core scaffold with defined substituents.
- Preparation Method Claims: Detailing synthesis routes to ensure enforceability against production processes.
- Use Claims: Claiming the specific use of the compound for particular conditions.
