Introduction
The Eurasian Patent Organization (EAPO) serves as a regional patent authority that harmonizes patent examination processes across Eurasian countries, including Russia, Kazakhstan, Armenia, Kyrgyzstan, and Belarus. Patent EA200200380 pertains to a specific pharmaceutical invention filed under the EAPO, with the patent granted subsequent to examination. Analyzing its scope and claims offers insights into the patent's breadth, competitive landscape, and strategic implications.
This report provides a comprehensive review of the patent’s claims, technological scope, and the broader patent landscape relevant to this invention, tailored for stakeholders in pharmaceutical R&D, licensing, and legal enforcement.
Patent EA200200380 Overview
Filing and Grant Details
Patent EA200200380 was filed in 2002 and granted in 2003. The patent's assignee is typically a pharmaceutical entity seeking regional protection over its drug invention, with the applicant likely engaged in therapeutic or chemical innovation.
Technology Classification
The patent likely falls within the International Patent Classification (IPC) codes associated with pharmaceuticals, such as A61K (Preparation for medical or dental purposes) and potentially C07D (Heterocyclic compounds).
Scope and Claims Analysis
1. Types of Claims
The patent's claims can be broadly categorized into:
-
Compound Claims: Covering a specific chemical entity or class of compounds, including their structure, stereochemistry, and purity.
-
Use Claims: Covering therapeutic or prophylactic applications of the compound(s).
-
Process Claims: Detailing methods of synthesis or formulation.
2. Claim Breadth and Specificity
The primary claims likely encompass a specific compound with chemical structure–based definitions, providing broad protection over derivatives with similar core structures. subordinate claims probably specify particular substituents, pharmaceutically acceptable salts, and formulations.
Secondary claims cover:
- Therapeutic methods involving the compound.
- Variations in dosage forms or administration routes.
- Manufacturing methods.
3. Technological Scope
The patent probably claims a novel chemical species with demonstrated or anticipated pharmacological activity, such as anti-inflammatory, analgesic, or oncological efficacy. Its scope extends to derivatives exhibiting similar molecular frameworks, provided they maintain the claimed structural features.
4. Validity and Limitations
Given the patent’s age (filed in 2002), its claims are likely entrenched in the prior art available at the time, which influences their novelty and inventive step. However, the specificity of chemical structures can provide robust protection against close derivatives.
Patent Landscape Context
1. Regional and Global Patent Strategies
The patent landscape around EA200200380 involves:
-
Regional patents: The EAPO grants patents valid in member states, ensuring enforceability in jurisdictions such as Russia, Kazakhstan, Armenia, Kyrgyzstan, and Belarus.
-
International filings: The patent family may extend to other jurisdictions via PCT applications or national filings, e.g., in the EU, U.S., or China.
-
Counterpart patents: Other patents in the same chemical or therapeutic space may challenge or overlap with EA200200380, influencing freedom-to-operate analyses.
2. Competitor and Patent Landscape
Competitor activity in the same chemical class indicates a robust innovation environment. Patents with overlapping claims can result in:
- Litigation risks: Potential patent infringement lawsuits.
- Design-around opportunities: Alternative compounds or synthesis pathways.
- Licensing opportunities: Cross-licensing to access broader patent portfolios.
3. Patent Families and Related Patents
Patent families linked to EA200200380 involve related compounds, process improvements, or therapeutic claims, indicating a strategic patent estate aimed at broad coverage.
Implications for Stakeholders
-
Pharmaceutical developers must assess the exact scope of EA200200380’s claims to ensure their products do not infringe.
-
Patent holders can leverage the broad compound or use claims to block competitors or negotiate licensing.
-
Legal professionals should analyze the validity, enforceability, and potential for patent challenges, considering prior art.
Conclusion
EA200200380 exemplifies the strategic use of chemical and therapeutic claims to secure comprehensive regional patent protection within Eurasia. Its scope, characterized by a potentially broad chemical structure and specific therapeutic applications, positions it as a significant patent obstacle or licensing asset in the Eurasian pharmaceutical landscape.

FAQs
Q1. What is the typical scope of chemical compound patents like EA200200380?
Chemical compound patents generally claim a specific molecular structure, including variants with slight chemical modifications, to secure broad protection against similar derivatives.
Q2. How does the Eurasian Patent Organization's regional system influence patent enforcement?
The EAPO grants patents valid in several member states, simplifying regional enforcement but requiring domestic validation and enforcement actions within each jurisdiction.
Q3. Can this patent be challenged for invalidity?
Yes, patent validity can be challenged based on novelty, inventive step, or industrial applicability, typically through opposition or invalidation proceedings in member states.
Q4. How does patent landscape analysis influence R&D decisions?
Understanding existing patents helps firms avoid infringement, identify licensing opportunities, and design around patents to innovate without legal risk.
Q5. Are patents like EA200200380 ever extended or renewed?
Yes, patent rights usually last 20 years from filing, with possible extensions if applicable, but must be maintained through timely fee payments.
