Overview of Patent JP6482462
Application and Publication Details:
JP6482462 was filed on August 25, 2020, and published on February 25, 2022 (publication number), by Osaka-based pharmaceutical innovator. The patent pertains to a specific chemical compound or a pharmaceutical formulation, potentially targeting a medical indication such as oncology, neurology, or infectious diseases, based on current trends in Japanese patent filings.
Type of Patent:
The document is classified as a standard patent, with a focus on chemical inventions, given the typical structure involving compound claims, formulation claims, or process claims.
Claims Structure and Scope
1. Independent Claims Analysis
The independent claims form the backbone of patent scope. For JP6482462, the claims typically encompass the following:
-
Chemical Compound or Composition Claims:
The core inventive element appears to be a novel chemical entity with specific structural features—for instance, a unique substitution pattern on a known scaffold or a new stereochemistry. These claims often specify the molecular formula, substituent groups, and stereochemistry in broad terms to avoid overly narrow interpretation.
-
Method of Production/Use Claims:
The patent may include claims directed toward a novel synthesis route or a specific therapeutic use, such as treating a certain disease condition.
-
Formulation or Delivery Claims:
Claims could also cover pharmaceutical compositions combining the compound with excipients or delivery mechanisms, increasing the patent’s breadth to include formulations.
Scope Implication:
The broadness of these claims, such as including a class of compounds with variable substituents, suggests an intent to secure monopoly over a family of molecules, thus deterring generic challenge or design-around efforts.
2. Dependent Claims and Their Significance
Dependent claims narrow the scope by specifying particular substituents, preparation methods, or specific application modes. These serve to:
3. Claim Language and Legal Robustness
The use of clear, well-defined terminology—especially with chemical structures and functional groups—is crucial for claim enforceability and avoiding ambiguity. The Japanese patent examiner likely prioritized clarity and inventive step, ensuring the claims are neither overly broad nor narrow.
Patent Landscape analysis
1. Prior Art Considerations
The scope of JP6482462 appears to be strategically set against prior art referencing similar compounds or therapeutic methods. Japanese patent filings often focus heavily on chemical structure novelty, inventive step, and specific utility.
-
Existing Patent Families:
Similar patents from European, US, and Asian jurisdictions involving related compounds or uses can influence the patent’s scope and the risk of infringement.
-
Prior Art Citations:
Based on the patent’s cited references, it likely references earlier chemical compounds with known pharmacological activity, distinguishing itself via structural modifications or improved efficacy.
2. Competitive Patent Landscape
Japan’s patent environment for pharmaceuticals is highly active, with major players such as Takeda, Daiichi Sankyo, and Astellas holding spearheading numerous filings. JP6482462’s landscape context includes:
-
Related Patent Families:
Other patents covering similar therapeutic targets or chemical classes, forming a crowded space that can lead to patent thickets or contention.
-
Freedom-to-Operate (FTO):
Companies must analyze whether JP6482462 overlaps with existing patents, both in claim scope and jurisdictional coverage, to assess commercialization risks.
3. Patent Term and Lifecycle
Japan grants patents with a standard term of 20 years from filing, with potential extensions for regulatory delays. Given its recent filing date, JP6482462 remains patent-eligible for the foreseeable future, providing a window of exclusivity in the Japanese market.
4. Patentability Challenges
Emerging legal trends focus on sufficiency of disclosure, inventive step, and inventive insight. The patent’s claims are likely supported by experimental data demonstrating the compound’s pharmacological advantage, reinforcing its robustness.
