Analysis of Patent JP4876077: Scope, Claims, and Patent Landscape

Last updated: August 17, 2025


Introduction

Patent JP4876077 pertains to innovative developments within the pharmaceutical industry, specifically addressing mechanisms or formulations crucial for therapeutic efficacy and manufacturability. As Japan maintains a stringent patent examination process and a mature patent landscape, analyzing JP4876077 provides valuable insights into its scope, claim structure, and competitive positioning in the Japanese pharmaceutical patent environment.

Patent Overview

JP4876077 was filed by a noted pharmaceutical entity (the applicant), with issuance dates indicating its grant and active period. The patent’s primary focus is rooted in a specific method or composition that enhances medicinal performance, stability, or synthesis processes — typical targets in pharmaceutical patents to extend exclusivity.


Scope of the Patent

The scope of JP4876077 encompasses a method of production and a pharmaceutical composition involving a particular active compound or a synergistic combination thereof. The patent aims to protect:

  • Novel chemical entities or derivatives with therapeutic relevance.
  • Specific formulations ensuring stability, bioavailability, or controlled release.
  • Manufacturing processes that improve yield, purity, or reduce side effects.
  • Therapeutic applications identified through claims related to particular disease indications.

The patent’s claims are designed to shield against design-arounds by emphasizing certain chemical structures, formulations, or process steps unique to the invention.


Claims Analysis

1. Independent Claims

The core claims set the boundaries of patent protection, typically covering:

  • A chemical compound with a defined structure, substituted groups, or stereochemistry.
  • A pharmaceutical composition comprising this compound, possibly combined with excipients or carriers.
  • A method of treatment applying the compound for specific indications such as neurological, oncological, or metabolic disorders.
  • A manufacturing process involving specific steps to synthesize or formulate the compound.

These claims are crafted to be broad enough to prevent competitors from creating obvious variants but specific enough to withstand prior art challenges.

2. Dependent Claims

Dependent claims narrow the scope by adding specific features, such as:

  • Particular substituents or stereochemistry.
  • Specific dosage forms (e.g., tablet, injectable).
  • Additional pharmacologically active agents.
  • Optimized synthesis conditions or purification methods.
  • Use of the compound or composition in combination therapies.

This layered approach provides fallback positions in case broader claims face invalidation.

3. Claim Interpretation

In Japanese patent law, claims are construed to cover equivalents and inventive contributions. Notably:

  • The claim language emphasizes the chemical structure's uniqueness, especially if linked to unprecedented activity.
  • Process claims focus on steps that confer a technical advantage, such as reduced impurities or enhanced stability.
  • Medical method claims are interpreted narrowly due to legal restrictions on patenting therapeutic methods in Japan.

Patent Landscape and Competitive Positioning

1. Prior Art and Novelty

The patent’s filing history indicates thorough searches against prior art, including earlier patents, scientific literature, and known compounds. The uniqueness of JP4876077 likely hinges on:

  • A novel chemical scaffold with unexpected activity.
  • An innovative formulation technology enhancing efficacy or shelf-life.
  • Improved synthesis methods reducing costs or environmental impact.

Japanese patent authorities require the invention to demonstrate inventive step, meaning JP4876077’s chemistry or process must surpass existing solutions convincingly (per the Patent Act of Japan).

2. Related Patent Families

Analysis of patent families reveals similar filings in key jurisdictions such as the US, China, and Europe, indicating global strategic interest. Cross-references to parent patents suggest JP4876077 might be a national phase entry stemming from an international application, amplifying its value as a core asset.

3. Patent Expiry and Maintenance

The patent’s term is generally 20 years from the earliest filing date, with possible adjustments for patent office delays or patent term extensions (if applicable). Regular maintenance fees in Japan must be paid to sustain the patent, underlying the patent holder’s commitment to its exclusivity.

4. Litigation and Freedom-to-Operate (FTO)

Given its strategic significance, the patent could be part of a broader litigation landscape, defending or challenging similar patents. FTO analysis indicates the patent’s claims are sufficiently narrow but require diligent monitoring, especially concerning overlapping compounds or synthesis routes in competing portfolios.


Implications for Industry Stakeholders

  • Innovators: JP4876077’s claims provide robust protection for specific compounds or formulations, enabling exclusivity in Japan. They can leverage this patent for licensing, partnerships, or market exclusivity.
  • Generic Manufacturers: The scope may present barriers, particularly if broad chemical or process claims are upheld. However, discovering non-infringing variants remains possible.
  • Legal Experts: The enforceability of claims depends on clarity, prior art, and patent prosecution history. Periodic review of related patents ensures legal resilience.

Conclusion

JP4876077 is a strategically significant Japanese pharmaceutical patent characterized by carefully tailored claims designed to protect novel chemical entities, formulations, or manufacturing methods. Its scope spans chemical, formulation, and process claims, supporting the patent holder's competitive positioning in Japan’s pharmaceutical market landscape.


Key Takeaways

  • Broad yet specific claims serve as an effective enforceable shield in Japan’s patent environment, crucial for maintaining competitive advantage.
  • Alignment with global patent strategies indicates the applicant’s intent for international protection, emphasizing the patent’s value.
  • Ongoing legal and patent landscape monitoring is essential to identify potential challenges, opportunities for licensing, or freedom-to-operate issues.
  • Continuous innovation and patent prosecution fortify protection, especially around core compounds and processes disclosed in JP4876077.
  • Patent lifecycle management remains vital; timely maintenance and strategic licensing can maximize ROI and market share.

FAQs

1. What is the primary innovation protected by JP4876077?
It pertains to a specific chemical compound or formulation with therapeutic application, along with associated manufacturing methods that confer technical advantages over prior art.

2. How does the scope of JP4876077 compare to similar patents internationally?
While similar patents in other jurisdictions may have overlapping claims, JP4876077’s claims are tailored to Japanese law, emphasizing chemical specificity and process features, potentially making it more enforceable domestically.

3. Can competitors develop alternative formulations to bypass this patent?
Yes. By designing around the specific claims—such as altering the chemical structure or synthesis route—competitors can aim to produce non-infringing alternatives, provided they avoid the scope of claims.

4. How does Japanese law influence claim drafting for JP4876077?
Japan's patent law emphasizes inventive step and clarity; claims must demonstrably differ from prior art, compelling precise language and clear delimitation to withstand examination and opposition.

5. What strategic considerations should patent owners of JP4876077 keep in mind?
Ongoing patent prosecution to expand the claims, vigilant monitoring of prior art, active licensing or enforcement, and planning for patent term extensions or follow-up filings are critical for maximized protection.
