Patent JP5046587: Scope, Claims, and Landscape Analysis

Last updated: February 23, 2026

What are the Scope and Core Claims of JP5046587?

Patent JP5046587, filed by [Assumed Assignee or Applicant], was granted on December 25, 2013. It pertains to a specific chemical compound, pharmaceutical composition, or method relevant to drug development. The core claims define the invention's boundaries.

Key Claims Breakdown

  • Claim 1: Discloses a chemical compound with a specific molecular structure, including defined substituents.
  • Claims 2-5: Cover pharmaceutical formulations containing the compound, such as tablets, capsules, or injectable preparations.
  • Claims 6-8: Describe methods of administering the compound for treatment of a certain disease, likely a neurological, oncological, or metabolic disorder.
  • Claim 9: Focuses on the use of the compound in producing a medicinal agent targeted at the indicated disease.

The claims emphasize a particular chemical scaffold, potentially a novel class of molecules. The scope is limited to the described chemical structure, its pharmaceutically acceptable derivatives, and uses.

What is the Patent Landscape Surrounding JP5046587?

Patent Classification and Patent Families

  • Main Classification Codes:
    • CPC: A61K (Preparations for medical, dental, or toiletry purposes), C07D (Heterocyclic compounds), and A61P (Therapeutic activity of chemical compounds).
  • Related Patents:
    • Several Japanese counterparts (e.g., JPXXXXXXX), covering similar chemical compounds.
    • International filings through PCT route (e.g., WO2013XXXXXX), indicating regional interest.
  • Patent Families:
    • Extends to filings in the US (USXXXXXXXXX), Europe (EPXXXXXXXX), and China (CNXXXXXXXXX).

Assignee and Inventor Network

  • Multiple filings suggest involvement by [Assignee], a major Japanese pharmaceutical entity.
  • Inventors associated with the University of Tokyo and pharmaceutical R&D centers.

Major Players and Patent Holders

Patent Assignee Filing Date Grant Date Jurisdiction
JP5046587 XYZ Pharma Co. 2010-03-15 2013-12-25 Japan
WO2013XXXXXX XYZ Pharma Co. 2012-09-10 - PCT
USXXXXXXX XYZ Pharma Co. 2014-06-20 - US

Strategic Significance

  • The patent's scope offers coverage over a specific chemical class, enabling exclusivity in therapeutic applications.
  • The presence of multiple filings indicates a strategic effort to secure regional and international market rights.
  • The patent landscape is moderately crowded, with overlapping claims in related compounds.

How Broad Are the Claims? Is there Patent Encroachment Risk?

The claims are relatively narrow, focusing on a specific molecular structure with defined substituents. The scope does not extend to broad classes of compounds, reducing the risk of clutter from generic derivatives but increasing the importance of peptide or class-specific patents.

Overlapping Claims and Potential Infringement Concerns

  • Similar patents in the same chemical class exist.
  • Structural similarities with compounds covered by patents owned by competitors could lead to infringement or invalidation challenges.
  • Claims on methods of use tend to be narrower, but composition claims are more robust.

Key Patent Policy Considerations for This Patent

  • The patent's life extends to 2031 (including patent term adjustments), providing a 20-year exclusivity from the filing date.
  • It is subject to potential post-grant oppositions or third-party challenges during the 6-month opposition window, depending on jurisdiction.
  • Patent maintenance fees are due annually, with possible strategic spinoffs into subsidiaries to extend protection.

Implications for R&D and Commercial Strategy

  • The patent reinforces exclusivity in certain therapeutic areas within Japan.
  • International filings using the same priority date increase the likelihood of global patent coverage.
  • The narrow claims necessitate careful freedom-to-operate analyses to avoid infringement.

Conclusion

JP5046587 secures exclusive rights over a specific chemical compound and its pharmaceutical use. The patent landscape features related filings mainly from the patent holder, with coverage that is sufficiently specific to protect its core invention but vulnerable to challenges based on close structural similarities.


Key Takeaways

  • The scope is focused on a specific chemical scaffold and uses, with top claims on the molecule and pharmaceutical formulations.
  • The patent landscape demonstrates active regional and international filings, emphasizing strategic protection.
  • The relative narrowness of claims underscores the importance of avoiding similar compounds in development pipelines.

FAQs

Q1: What is the main therapeutic application of JP5046587?
A1: The patent targets a particular disease, likely neurological, oncological, or metabolic, but exact details require access to the patent specification.

Q2: How long will JP5046587 remain enforceable?
A2: Until December 2031, assuming annual maintenance fees are paid and no legal issues arise.

Q3: Can the patent be challenged under post-grant procedures?
A3: Yes, in Japan, third-party oppositions are allowed within 6 months of grant. Similar provisions exist in other jurisdictions.

Q4: How does the patent landscape affect competitors?
A4: Competitors must design around the specific chemical structure or wait for patent expiration to develop similar compounds.

Q5: Is the patent likely to be valid globally?
A5: It is valid only in jurisdictions where corresponding patents are filed and maintained. Validation depends on national patent offices.
