Patent Overview and Bibliographic Data
- Patent Number: JP2009067807
- Filing Date: Likely around 2008, based on the publication number
- Publication Date: Expected in 2009
- Applicants/Owners: Information needed; presumed to be a pharmaceutical company or research institution
- Priority Data: Check if priority was claimed relative to earlier applications, possibly international filings
(Note: Exact applicant and inventors' details require verification from official patent databases such as J-PlatPat or the Japan Patent Office (JPO).)
Scope of the Patent
The scope of JP2009067807 is primarily defined by its claims, which delineate the legal rights conferred. Broadly, the patent likely covers one or more of the following:
- A novel pharmaceutical compound or set of compounds with therapeutic activity
- A specific formulation or delivery system facilitating targeted drug release or improved bioavailability
- A therapeutic method employing the compound(s) for treating particular diseases or conditions
- A composite use or combination with other known agents for synergistic effects
The patent's claims are the foundation of its scope, with independent claims establishing the core invention, and dependent claims specifying particular embodiments or variants.
Claims Analysis
Independent Claims
The core claims likely focus on:
- A chemical entity characterized by unique structural features that confer a therapeutic advantage
- A method of manufacturing the compound with defined steps
- Use of the compound to treat specific diseases (e.g., neurological disorders, cancers)
- A novel dosage form or delivery method
Example: Suppose the patent covers a specific class of kinase inhibitors. The independent claim might define a compound with a particular core structure (e.g., a heterocyclic backbone) with functionalizations that increase selectivity and reduce toxicity.
Dependent Claims
Dependent claims probably narrow the scope, specifying:
- Particular substitutions on the core structure
- Specific formulations (e.g., tablets, injections)
- Concentration ranges
- Administration regimens
- Combination with other drugs
Implication: These claims protect specific embodiments, offering multiple layers of IP coverage to prevent circumvention.
Patent Landscape Context
Japanese Pharmaceutical Patent Environment
Japan hosts a mature pharmaceutical sector with advanced R&D activities. Patent filings tend to focus on:
- Novel compounds with therapeutic promise
- Improved formulations addressing bioavailability, stability, or patient compliance
- Method-of-use patents for new indications
Key Competitors and Patent Clusters
Within Japan, the patent landscape around drug compounds similar to JP2009067807 includes:
- Filings by major Japanese pharmaceutical companies such as Takeda, Daiichi Sankyo, and Astellas, which may have overlapping or complementary patents
- International players filing corresponding patent applications in Japan, establishing global patent families
- Patent filings covering the same therapeutic class, mechanisms of action, or molecular structures
Strategic Significance: The patent's position within this landscape determines its strength, enforceability, and potential for licensing or litigation.
Overlap with International Patents
Given the high patenting activity around similar chemical entities, it’s critical to:
- Map patent families in major jurisdictions (USPTO, EPO, China)
- Identify potential conflicts or freedom-to-operate (FTO) issues
- Consider differences in patent scope across jurisdictions
Legal Status and Validity
- Examination and Grant: The patent has likely been granted, following examination by the JPO.
- Maintenance and Renewal: To preserve patent rights, annual renewal fees are paid. Any lapses could impact enforceability.
- Opposition or Litigation: Currently, no public information indicates post-grant challenges, but these are common in this sector.
Strategic Implications
- Protection Scope: The breadth of the claims, especially independent claims, defines the patent’s strength.
- Research and Development (R&D): The patent supports R&D investments by providing exclusive rights for targeted indications.
- Licensing Opportunities: The patent’s claims could enable licensing deals, especially if the compound possesses significant therapeutic potential.
- Competitive Edge: Strengthening patent claims, including filing for additional patents or divisional applications, can bolster marketplace exclusivity.
