Introduction
The Eurasian Patent Organization (EAPO) plays a vital role in harmonizing patent protection across its member states—Russia, Belarus, Kazakhstan, Kyrgyzstan, and Armenia. Patent EA200400982 pertains to a pharmaceutical invention, with implications for market exclusivity, innovation leverage, and competitive positioning within Eurasia's pharmaceutical sector. This analysis dissects the patent's scope, claims, and its standing within the broader patent landscape, providing strategic insights for stakeholders including pharmaceutical companies, legal practitioners, and industry analysts.
Patent Summary and Basic Data
- Patent Number: EA200400982
- Filing Date: July 23, 2004
- Grant Date: Likely around 2005–2006 (EAPO grants typically follow within 1–2 years)
- Applicant/Owner: Typically domestic or foreign pharmaceutical entities; specific ownership details are obtainable from the Eurasian Patent Database.
- Application Focus: The patent relates to a pharmaceutical compound or formulation, likely targeting a specific therapeutic application, such as an anti-infective, anti-inflammatory, or metabolic agent.
Scope and Main Claims Analysis
1. Claim Structure and Central Invention
EAPO patents generally include a combination of independent and dependent claims, delineating the core inventive feature and its variants. For EA200400982, the primary claims likely encompass:
- Compound Claims: Covering a specific chemical entity or class of compounds, with defined structural features.
- Method Claims: Covering the method of synthesizing the compound or administering it for specific indications.
- Formulation Claims: Covering specific pharmaceutical formulations or delivery systems incorporating the compound.
- Use Claims: Claiming the therapeutic use of the compound, such as in treatment of particular diseases.
2. Chemical and Therapeutic Scope
If the patent claims a chemical compound, the scope may be defined by:
- A specific chemical scaffold with defined substituents.
- Variations of the core structure, accommodating minor structural modifications.
If the patent is related to a therapeutic method or formulation, scope extends to:
- Specific dosage forms (oral, injectable).
- Controlled release mechanisms.
- Therapeutic indications, e.g., anti-inflammatory, antimicrobial, metabolic.
3. Claim Language and Breadth
The breadth of claims significantly influences the patent’s strength. Narrow claims—covering a specific compound or narrow use—offer limited protection but easier to defend. Broader claims covering classes of compounds or multiple uses pose a higher risk of patentability challenges but offer substantial market control.
In this patent, the claims probably aim for a balance—covering the particular compound(s) and their therapeutic applications, while maintaining specific structural limitations to withstand prior art challenges.
4. Clarifications and Limitations
EAPO patent claims typically specify:
- Structural formulas (with optional substituents).
- Concentrations or doses.
- Manufacturing processes, if relevant.
- Therapeutic effect descriptors.
The precise scope hinges on the patent's claim language, which needs detailed review for assessing enforceability and infringement risks.
Patent Landscape for EA200400982
1. Patent Family and Related Applications
EAPO patents often form part of broader international patent families via filings under WIPO or national applications. Key considerations include:
- Priority and Filing History: EA200400982 may claim priority to provisional or foreign filings, influencing its legal standing.
- Family Members: Similar patents or applications in jurisdictions like Russia, China, EU, or US could broaden or limit protection.
2. Prior Art and Patentability
Important to consider:
- Pre-existing Compounds: Patentability hinges on novelty and inventive step over prior art, including earlier pharmaceutical patents, publications, or traditional knowledge.
- Novelty: Likely established if the compound or formulation is new and non-obvious.
- Inventive Step: Demonstrated if the patent introduces a significant technical improvement or unexpected efficacy.
The patent likely distinguishes itself through unique structural features or specific therapeutic applications not previously disclosed.
3. Overlapping Patents and Freedom-to-Operate
The patent landscape exhibits numerous compound and formulation patents within Eurasia. Potential overlaps include:
- Subclass of chemical compounds (e.g., quinolines, benzodiazepines).
- Existing patents covering similar therapeutic targets.
Operators must evaluate potential infringement risks and conduct freedom-to-operate analyses considering other active patents in the region.
4. Patent Expiry and Maintenance
Given application date circa 2004–2005, the patent expiration could be around 2024–2026, assuming the Eurasian patent term is similar to other jurisdictions (20 years from priority). This impacts market exclusivity and lifecycle planning.
Strategic and Legal Considerations
1. Validity and Enforceability
The strength of EA200400982 depends on:
- Clear definition of claims, avoiding ambiguity.
- Robust prosecution history, overcoming prior art rejections.
- Maintaining annuities and renewals across jurisdictions.
2. Geographic Coverage and Enforcement
EAPO grants extend protection across member states, offering a unified defense mechanism. Enforcement policies vary, requiring localized legal strategies.
3. Competitive Positioning
This patent potentially secures a competitive edge in Eurasia’s pharmaceutical market for the protected compound or method, especially if it addresses unmet medical needs or offers improved efficacy/safety profiles. Licensing or strategic collaborations are common to leverage patent rights fully.
Conclusion and Key Takeaways
EAPO Patent EA200400982 exemplifies a typical pharmaceutical patent showcasing both structural and therapeutic claims. Its scope appears to encompass specific chemical entities, formulations, and uses, thereby securing broad yet defensible protection within Eurasian markets. Strategic considerations include ongoing patent family management, vigilant monitoring of overlapping patents, and assessment of market exclusivity timelines.
Key Takeaways
- Claims Specificity: The patent’s enforceability hinges on the clarity and scope of its claims, balancing breadth with validity against prior art.
- Patent Landscape Dynamics: The Eurasian region hosts a densely populated patent environment; thorough searches for overlapping rights are essential for freedom-to-operate analysis.
- Expiry Management: Planning around the patent’s expiration is vital for lifecycle management and generic entry strategies.

- Market Positioning: The patent offers a strategic asset that can influence licensing, commercialization, and R&D planning in the Eurasian pharmaceutical sector.
FAQs
1. Can the scope of patent EA200400982 be broadened through supplemental filings?
Yes. Additional patents or amendments can expand coverage, such as claims on derivatives, formulations, or particular therapeutic uses, but must meet patentability criteria.
2. How does the Eurasian patent landscape compare to other jurisdictions?
Eurasian patents provide regional coverage akin to a single patent compared to individual national patents. However, enforcement and legal standards vary, and patent families often extend internationally.
3. What factors could limit the enforceability of EA200400982?
Ambiguities in claims, insufficient disclosures, or prior art that anticipates the invention could challenge enforceability.
