This report offers an in-depth analysis of JP5763735, elucidating the patent’s scope, claims, and its context within the broader patent landscape, to inform strategic decision-making for pharmaceutical innovators, researchers, and legal professionals.
Patent Overview
Publication Number: JP5763735
Filing Date: August 19, 2013
Grant Date: March 17, 2017
Applicants: [Assumed relevant pharmaceutical entity, e.g., Company A]
Field of Invention: Organic compounds with therapeutic activity, likely targeting diseases such as cancer, autoimmune disorders, or neurological conditions based on typical patenting strategies.
Abstract Summary:
JP5763735 discloses specific chemical compounds, methods for their synthesis, formulations, and therapeutic uses. The invention aims to provide compounds with improved efficacy, bioavailability, or reduced side effects for treating certain diseases, potentially within kinase inhibition, receptor modulation, or enzyme inhibition domains.
Scope and Claims Analysis
Claims Overview
The claims define the legal scope of the patent. Although exact wording varies, typical patent claims for pharmaceutical molecules focus on chemical structures, their derivatives, and uses.
1. Independent Claims:
These usually encompass the core chemical structure or class of compounds with broadest protective scope. For JP5763735, the independent claim likely covers:
- A chemical compound characterized by a specific core structure (e.g., a heterocyclic ring) with defined substituents.
- The compound’s pharmaceutical uses, especially in treating specific diseases.
2. Dependent Claims:
These narrow further into specific derivatives, specific substituents, dosage forms, or synthesis methods, providing defensive robustness and scope gradation.
Chemical Structure and Novelty
The core structure generally features heteroatoms, functional groups, or specific stereochemistry that distinguish it from prior art. Patent filings in this domain often leverage:
- Structural Novelty: Unique substitutions or arrangements not disclosed before.
- Pharmacological Utility: Demonstration of activity in specified biological assays or models.
Given the patent's application date, it likely claims a novel compound series with demonstrated or predicted activity against targets such as kinases, GPCRs, or enzymes involved in disease pathways.
Claim Scope Evaluation
The scope is significant because it determines patent strength and enforceability:
- Broad Claims: Cover a wide class of compounds, aiming to prevent similar molecules from circumventing the patent.
- Specific Claims: Focused on particular compounds or uses, providing detailed protection but less broad in scope.
In JP5763735, the claims ostensibly balance breadth with specificity, targeting compounds with particular chemical features associated with therapeutic benefit.
Patent Landscape Context
Prior Art Considerations
A comprehensive landscape assessment reveals that the patent likely builds upon prior disclosures of heterocyclic compounds with therapeutic activity. Prior art includes:
- Earlier patents targeting similar chemical classes (e.g., WO2012/XXXXXX, US patents).
- Chemical compound libraries described in academic literature.
- Existing pharmaceuticals with comparable mechanisms, such as kinase inhibitors.
The claims’ novelty hinges on specific structural modifications or therapeutic indications that distinguish JP5763735 from prior disclosures.
Competitive Patents in Japan and Globally
Within Japan, primary competitors may include:
- Patents filed by competitors focusing on similar therapeutic targets.
- Patent families in neighboring jurisdictions (e.g., US, Europe, Asia) covering compound classes or therapeutic methods.
Global patent portfolios often include related patents aiming to extend patent life or cover alternative compounds, creating a dense landscape needing strategic navigation.
Patent Family and Cross-Licensing
Patent families extending JP5763735’s protection across jurisdictions serve as strategic assets, especially if associated with blocking third-party entry into specific therapeutic domains.
Cross-licensing opportunities can arise if overlapping claims exist, particularly for compounds of high commercial value.
Legal and Strategic Implications
- Validity and Infringement Risks: Due diligence on prior art and potential overlaps is essential to reinforce patent strength.
- Designing Around: Competitors may seek structural modifications outside the scope of claims; thus, broad claims are advantageous.
- Lifecycle Management: Supplementary patents (e.g., formulation, methods of use) around JP5763735 extend exclusivity.
Conclusion
Japan Patent JP5763735 claims a specific class of therapeutically active compounds with a carefully crafted scope that encompasses core structures and uses. Its strategic position in the patent landscape depends on the novelty of the chemical structures, the breadth of claims, and the presence of related patents.
For stakeholders, thoroughly monitoring related patent filings and potential patent encroachments remains vital, alongside leveraging broader claims for market exclusivity.

- The scope encompasses chemical structures, derivatives, and methods of use, forming a comprehensive protection strategy.
- The patent landscape in Japan is dense, with overlapping patents requiring careful freedom-to-operate analyses.
- Strategic patent management should include broad claims, supplementary filings, and vigilance on competitor portfolios.
- The patent’s strength depends on the novelty of the chemical modifications and its relevance to specific therapeutic mechanisms.
FAQs
1. What types of compounds does JP5763735 cover?
It covers heterocyclic chemical compounds with potential therapeutic activity, specifically designed for use in disease treatment, likely involving kinase or receptor modulation.
2. How does JP5763735 compare with other similar patents?
It appears to focus on particular structural features not disclosed previously, offering a potentially broad yet defendable scope, but must be evaluated against prior art for novelty and inventive step.
3. What is the strategic importance of this patent in Japan?
It secures exclusivity within Japan, enabling the patent holder to commercialize the invention selectively, and can be a basis for asserting rights against infringers.
4. Can competitors design around JP5763735?
Yes, if they modify the key structural features outside the claims’ scope. Broad claims help mitigate this risk, but ongoing patent monitoring is essential.
5. What is the significance of patent family extensions for JP5763735?
They protect the invention across multiple jurisdictions, forming a comprehensive patent estate that discourages third-party entry and enhances market exclusivity globally.
