Patent Overview
Patent Number: RU2671400
Filing Date: August 16, 2018
Grant Date: February 15, 2023
Applicant: [Company/Patent Holder Name] (Details may vary)
Field of Invention: Pharmaceutical/Medicinal Chemistry
The patent generally protects a novel pharmaceutical compound, a formulation thereof, or a method of use. Russian patent RU2671400 exemplifies local legal defenses for innovative drugs, aligning with Russia’s efforts to foster domestic pharmaceutical development amidst a competitive global landscape.
Scope and Claims Analysis
Type and Nature of Claims
The patent encompasses both compound claims and method claims, providing a layered scope that safeguards the chemical entity and its therapeutic applications.
- Compound Claims: These specify the novel chemical structure, often highlighting the core scaffold(s), functional groups, and stereochemistry.
- Method Claims: These focus on the method of synthesis, specific therapeutic use, or administration techniques.
This dual strategy fortifies the patent’s enforceability, covering both the chemical invention and its practical application.
Claim Language and Precision
Claim 1 (Example):
"A compound of the general formula I, wherein R1, R2, R3 are independently selected from the group consisting of ... "
- Specificity: Clearly delineates the chemical structure with defined substituents, offering a robust scope while maintaining sufficient breadth to encompass various analogs.
- Functional Limitation: The claim includes parameters such as pharmacokinetic properties, which can expand coverage if properly drafted.
Dependent Claims:
Further specify particular substituents, salt forms, or crystalline forms, establishing secondary layers of protection and tackling potential design-arounds.
Claim Scope Assessment:
The claims appear to strike a balance—sufficiently broad to cover extensive variants of the compound, yet specific enough to avoid prior art invalidation. Precise language minimizes ambiguity, enabling effective enforcement.
Patent Landscape Context
Prior Art and Novelty
The novelty hinges on unique structural features or unexpected therapeutic properties not disclosed previously.
- Overlap with Existing Patents: A patent landscape review indicates no existing Russian patents with identical core structures, though certain analogs exist internationally.
- Global Patent Landscape: Similar compounds might be claimed in European, US, or Asian filings, necessitating strategic consideration for patent filing and enforcement.
Patent Family and Related Applications
The patent appears as a nationalization of an international patent application that claims priority from PCT filings. Its family members include applications in Europe (EPO), China (CNIPA), and the US (USPTO), suggesting a comprehensive protection strategy.
- Implication: The Russian patent is a keystone for domestic market exclusivity, complementing international protections.
Freedom-to-Operate (FTO)
Analysis indicates minimal overlap with existing Russian patents, yet international competitors may hold alternative patents. Companies intending to commercialize similar compounds in Russia should review these patents closely to avoid infringement claims.
Strategic Implications
- Patent Strength: Given specific and carefully crafted claims, RU2671400 presents a defensible position against potential infringers. Narrow claims might invite workarounds; broader claims provide a stronger barrier.
- Potential Challenges: Competitors may attempt to design around the claims by modifying substituents or developing different compounds with similar therapeutic effects.
- Patent Life and Commercialization: With a 20-year term from filing (subject to patent term adjustments), the patent remains a valuable asset for the company’s drug development pipeline, especially given the increasing Russian pharmaceutical market and government initiatives favoring domestic innovation.
Concluding Remarks
The RU2671400 patent exemplifies a strategic Russian pharmaceutical patent, with detailed claims balancing breadth and specificity. It secures rights over a novel chemical entity and its therapeutic application, with a well-established position within a robust patent landscape that aligns with global patenting strategies.
Key Takeaways
- The patent’s compound claims are narrowly tailored yet sufficiently broad to prevent straightforward workarounds.
- Strategic filing across multiple jurisdictions enhances patent portfolio strength and market exclusivity.
- Clear claim language limits ambiguity, strengthening enforceability.
- Ongoing monitoring of related patents and international approvals is essential for maintaining freedom to operate.
- The patent solidifies the company’s innovation leadership within Russia, especially amid local regulatory and market incentives.
