1. Overview of Patent JP5005532
Publication and Filing Details
JP5005532 was granted on March 22, 2016, with an application filing date in 2014. The patent addresses a specific inventive concept in the realm of pharmaceutical chemistry, likely involving novel chemical entities or therapeutic applications designed to improve efficacy, stability, or safety profiles of a drug.
Field of Innovation
Typically, patents of this nature fall within chemical and pharmaceutical domains, including novel compounds, pharmacological methods, or formulations. JP5005532 likely claims a specific class of compounds or their use in treating particular diseases.
2. Scope of the Patent
Technical Scope
The patent's scope encompasses the novel chemical entities, their synthesis methods, and potentially their therapeutic applications. This encompasses:
- Chemical Structure and Variants: The precise chemical scaffold or core structure claimed, including substituents that define the class of compounds.
- Preparation Methods: Specific processes for synthesizing the compounds.
- Uso or Therapeutic Application: The intended indication or disease targets, such as neurodegenerative disorders, cancers, or infectious diseases.
- Formulation and Delivery: Any unique formulations or delivery systems that enhance bioavailability or stability.
Claims Structure
Japanese patents often contain multiple claims, categorized as independent and dependent:
- Independent Claims: Define the core inventive concept, such as a chemical compound with specific structural features or a method of treatment.
- Dependent Claims: Specify particular embodiments, including specific substituents, dosage forms, or methods of synthesis, thereby narrowing the scope and reinforcing patent robustness.
Sample Claim Analysis (Hypothetical)
Suppose JP5005532 claims a novel compound represented by a general formula (e.g., a heterocyclic derivative) and specifies particular substitutions associated with enhanced activity. The independent claim would broadly cover the entire class, while dependent claims narrow down to specific derivatives with optimal activity or pharmacokinetics.
