Overview of Patent RU2519664
Filing and Grant Details
- Application Number: RU2519664
- Filing Date: Exact date unspecified in the prompt; typical patent grant timelines suggest early 2010s
- Grant Date: Not specified; assuming possession of legal protection, conforming to standard Russian patent procedures

Technology Area
The patent resides within the pharmaceutical sector, covering a specific compound, formulation, or method of use related to a therapeutic or diagnostic application prevalent in Russian or international markets.
Scope of the Patent
1. Nature of the Invention
Based on typical drug patenting practices in Russia and the general characteristics of RU2519664, the invention likely relates to:
- A novel chemical entity with therapeutic utility
- An improved formulation of an existing drug
- A new method of synthesis or use of a known compound
Without the specific patent document, the most probable scenario is that RU2519664 claims a specific chemical compound or a pharmaceutical composition with unique properties, possibly a new variation of a known active pharmaceutical ingredient (API).
2. Claim Structure and Types
- Independent Claims: Usually define the core invention broadly, covering the chemical compound(s), composition, or method. For example, “A compound of formula X,” “A pharmaceutical composition comprising compound Y,” or “A method of treating condition Z using compound Y.”
- Dependent Claims: Narrow the scope, specify particular substituents, formulations, dosages, or methods of use.
3. Claim Scope
The scope, as typical in Russian pharmaceutical patents, is often a balance between broad claims covering the core invention and narrow claims protecting specific embodiments. It may include:
- Chemical formulae representing the novel compounds
- Use claims covering the treatment of specific diseases
- Formulation claims, including excipients and delivery systems
- Method claims relating to synthesis or application
4. Patent Claim Language and Limitations
Russian patent claims are precise and often detail features such as stereochemistry, substituents, and functional groups, aiming to define a distinct inventive step. The language may include:
- Structural formulae
- Markush groups
- Definitions of pharmaceutical compositions
Patent Landscape and Prior Art Environment
1. Regional and Global Patent Landscape
Pharmaceutical inventions close to RU2519664 are often present in:
-
International Patent Classification (IPC) classes such as A61K (Preparation for medical, dental, or cosmetic purposes) and C07D (Heterocyclic compounds)
-
Patent families filed via the Patent Cooperation Treaty (PCT) or directly in major jurisdictions (e.g., EPO, US, China)
2. Prior Art and Patent Citations
The invention's novelty and inventive step are evaluated against prior art—both patent and non-patent literature. The patent examiner would have examined:
- Prior patents in Russia and abroad
- Scientific publications
- Existing formulations or API modifications
3. Overlaps and Freedom-to-Operate
Potential overlaps with existing patents depend on:
- Similarity of chemical structures or formulations
- Therapeutic indications
- Method of use claims
An FTO analysis reveals whether RU2519664 blocks generic development or whether there are freedom-to-operate pathways.
4. Patent Families and International Filings
- It is crucial to examine if RU2519664 belongs to a patent family with filings in the EPO, US, or Asian jurisdictions.
- An international patent family indicates strategic protection and broader market coverage.
Claims Analysis in Detail
1. Broadness and Specificity
If the independent claims are broad (e.g., covering a class of compounds), they provide extensive protection but may face challenges during patent examination for obviousness. Narrow claims targeting specific compounds or methods might be more defensible but limit scope.
2. Critical Claim Elements
- Structural features: substituents, functional groups
- Therapeutic application: specific disease states or tissue targeting
- Formulation characteristics: excipient composition, stability
3. Potential for Invalidity or Challenge
Claims that are overly broad or lack novelty may be susceptible to invalidation. Prior disclosures, general knowledge, or obvious modifications in known compounds can serve as prior art grounds.
Technical and Commercial Implications
1. Strategic Positioning
- The patent's scope indicates a focus on proprietary chemical entities or formulations.
- It likely serves as a foundation for exclusivity in the Russian market, potentially extending protections through supplementary patents or related filings.
2. Patent Enforcement & Litigation
- Clarifying the scope helps in defining infringement boundaries.
- The patent’s enforceability depends on claim language and prior art challenges.
3. Licensing Opportunities
- The patent may be a licensing asset for generic developers or multinational pharmaceutical companies aiming to introduce biosimilars or innovative formulations.
Conclusion and Recommendations
- For Innovators: Examining the specific claims reveals the patent's breadth and potential overlap with existing IP. Ensuring that product development does not infringe requires detailed analysis.
- For Generics: Identifying claim limitations helps in developing workarounds or designing around the patent.
- Legal Professionals: Validity and enforceability assessments hinge on the patent’s claim specificity and prior art.
Key Takeaways
- RU2519664 likely covers a specific chemical compound or pharmaceutical formulation with targeted therapeutic use.
- The claim scope balances broad chemical protection with specific embodiments, which influences enforcement and licensing strategies.
- The patent landscape shows prior art in similar chemical classes and formulations, emphasizing the need for detailed freedom-to-operate analysis.
- Broader patent families linked to RU2519664 could extend protection globally, impacting market entry strategies.
- Ongoing legal and technical evaluations should focus on claim validity, potential for infringement, and opportunities for patent oppositions or licensing.
FAQs
Q1: How does RU2519664 compare to similar international patents?
While the specific USPTO or EPO equivalents are not listed here, similar patents often involve structural modifications of APIs. Cross-referencing patent families can clarify overlaps and potential for international protection.
Q2: Can the claims be challenged for obviousness?
Yes. If prior art teaches similar compounds or formulations, the broad claims may be susceptible to invalidation due to obviousness.
Q3: What strategies can competitors use to bypass this patent?
Developing alternative chemical structures outside claimed Markush groups, altering formulations, or discovering new therapeutic indications can serve as effective workarounds.
Q4: How does patent RU2519664 impact generic drug development?
It might restrict generic formulations that contain the patented compound or use the protected method in Russia, necessitating careful FTO analysis.
Q5: Is the patent likely to be enforceable?
Enforceability depends on the robustness of the claims, clarity, and absence of prior art challenges. A detailed legal assessment is required to confirm.
