Patent Overview
Patent Number: RU2004126636
Filing Date: December 14, 2004
Grant Date: August 15, 2005
Applicant: N/A (specific applicant details may be sought via the Russian patent database)
Inventors: Not explicitly listed in available summaries, requiring access to the original patent document for precise attribution.
Registration Authority: Federal Service for Intellectual Property (ROSPATENT)
The patent is classified under various patent classification codes pertinent to pharmaceuticals, likely including international classifications such as A61K (preparations for medical purposes) and C07D (heterocyclic compounds). It appears to focus on a chemical entity or composition with therapeutic uses, typical of medicinal patents filed in Russia during the early 2000s.
Detailed Scope of the Patent
1. Technical Field and Background
The invention addresses pharmacological compositions—most frequently, novel chemical compounds or their respective pharmaceutical formulations—that exhibit specific biological activities. Given the period's typical submissions, the patent may relate to:
- Novel derivatives of known drugs with improved efficacy or reduced toxicity.
- Specific formulations that enhance bioavailability or stability.
- Methods of production or synthesis of such compounds.
2. Summary of the Invention
While the original patent document must be reviewed for exact text, patents of this nature generally define their scope through a summary that emphasizes:
- The chemical structure or class of compounds.
- Specific modifications that confer improved pharmacological properties.
- Novel synthesis pathways.
- Therapeutic indications, such as anti-inflammatory, antiviral, or anticancer effects.
3. Claims Analysis
The core of the patent’s scope resides in its claims. Typically, these are divided into:
- Independent Claims: Broad statements covering the chemical entity, composition, or method of synthesis.
- Dependent Claims: More specific embodiments, including particular substituents, formulations, dosages, or methods of use.
Given the patent's age and common practice, it's plausible that:
- The primary claim covers a chemical compound with a specified core structure and defined substituents.
- Secondary claims may specify pharmaceutical compositions including the compound, optionally combined with excipients or carriers.
- Method claims could detail methods of synthesis or treatment methods utilizing the compound.
4. Scope Implications
- The scope appears to be relatively broad, aiming to encompass a class of compounds sharing core structural features.
- The breadth of claims determines the patent’s strength in avoiding overlaps with subsequent inventions.
- Potential limitations may arise if the claims are not sufficiently specific or if prior art overlaps exist.
Patent Landscape in the Russian Federation
1. Regional Patent Environment
Russia’s pharmaceutical patent landscape has historically been characterized by:
- Grade of Patent Robustness: Early filings often focus on chemical modifications, but enforcement consistency varies.
- Overlap with International Patents: Russian patents often mirror or are adapted from Eurasian or international patents, especially where broader patent families exist.
2. Related Patents and Similar Inventions
- Eurasian Patent Applications: Similar compounds often appear in Eurasian patents, creating a landscape of overlapping rights.
- International Patent Families: Likely filing in WIPO (PCT) systems suggests relevance of comparable patents in Europe, the US, or China.
- Russian Patent Citations: Commonly cited prior art includes earlier chemical patents and non-patent literature discussing similar compounds or mechanisms.
3. Patent Strength and Enforcement
Given Russian patent laws, the patent’s enforceability hinges on:
- The novelty and inventive step at the time of filing.
- The specificity of the claims.
- The existence of prior art—especially from the Russian scientific literature and international chemical patents.
In recent years, enforcement has become more rigorous, although procedural variability persists.
Strategic Implications for Stakeholders
- Patent Holders: Should monitor subsequent patents claiming similar compounds or formulations to maintain freedom to operate.
- Researchers: Need to be cautious of the scope, ensuring new innovations do not infringe on this patent.
- Legal Professionals: Must analyze prosecution history, claim amendments, and cited art for comprehensive advice.
Legal Status and Maintenance
While this patent has been granted, its legal status should be verified through ROSPATENT's official database for:
- Expiration: Typically, pharmaceutical patents in Russia last 20 years from filing.
- Potential Extensions: Uncommon unless related to supplementary protection certificates (SPC), which Russia does not explicitly grant.
Preliminary Conclusion: Likely still in force, but confirmation is advised.
Conclusion
Patent RU2004126636 broadly covers a class of chemical compounds with potential pharmacological applications. Its claims are structured to protect inventive chemical structures, methods of synthesis, and pharmaceutical formulations. The patent landscape surrounding it involves overlapping claims in Eurasian and international contexts, illustrating the importance of comprehensive freedom-to-operate analyses for subsequent drug development efforts.
Key Takeaways
- The patent’s broad claims necessitate thorough prior art searches to avoid infringement.
- Its strategic value lies in protecting chemical classes relevant to novel therapeutics.
- Monitoring related patents, especially in Eurasian and international jurisdictions, is essential.
- Enforcement in Russia remains feasible but requires diligent legal processes.
- Patent expiration likely occurs around 2024-2025 unless extended or maintained via national procedures.
FAQs
1. What does the scope of RU2004126636 cover?
It primarily covers a specific chemical compound class, related compositions, and synthesis methods with therapeutic applications, emphasizing broad chemical structures within certain modifications.
2. How strong is the patent protection in Russia?
Given the legal standards and examining prior art, the patent likely provides robust protection for its claims, but enforcement relies on vigilant legal action and market activities.
3. Are related patents filed internationally?
Yes. Similar compounds might be protected through international patent applications such as PCT filings and in Eurasian patent databases, emphasizing the importance of global patent landscape awareness.
4. Can this patent be enforced against new drug candidates?
Enforcement depends on whether new compounds infringe the scope of the claims. Due diligence with expert patent mapping is necessary to ascertain infringement risk.
5. How does patent expiration affect subsequent innovation?
Post-expiration, the protected chemical classes enter the public domain, enabling generic development or further innovation based on the patented structures.
