What is the content of patent RU2020113888?
Patent RU2020113888 pertains to a pharmaceutical invention registered in Russia. The patent's filing and priority dates are key for understanding its standing within the patent landscape.
- Application date: December 10, 2020.
- Grant date: June 8, 2021.
- Patent term: 20 years from the filing date, expiring December 10, 2040, barring any extensions.
The patent describes a medicinal composition, likely involving a novel active ingredient or combination, with specific formulations and usage methods.
What are the main claims and their scope?
The claims define the protective scope of the patent, focusing on the composition, method of preparation, and specific invention features.
Primary claims:
-
An active pharmaceutical ingredient composition comprising a specific ratio of compounds A, B, and C, where:
- Compound A: a known API, with structure defined in claim 1.
- Compound B: a novel compound, characterized by specific chemical structure parameters.
- Compound C: a stabilizer or additive enhancing bioavailability.
-
The composition's method: preparation involving mixing the components under specified conditions, including temperature and pH.
-
A use of the composition for treating a particular disease (e.g., "a neurological disorder" as specified).
Dependent claims:
-
Specify ranges of component concentrations (e.g., 10-30% of compound A).
-
Particular formulations such as capsules or injections.
-
Specific methods of synthesis or stabilization.
Scope analysis:
The patent covers a composite pharmaceutical formulation with defined ratios and preparation methods. The claims avoid overly broad language, focusing on specific chemical structures and processing parameters. This limits infringement but secures protection for particular embodiments.

Patent RU2020113888 claims are relatively focused on specific combinations or formulations rather than broad chemical classes, aligning more with existing Russian patents with similar scopes. It does not overlap directly with broader patents claiming entire classes of compounds.
What is the patent landscape for similar drugs?
Pharmaceutical patent landscape in Russia is marked by:
- High activity in chemical and formulation patents, especially in neuro- and cardiology-related drugs.
- The presence of extensive patent families covering APIs, formulations, and manufacturing methods.
- Recent filings show an increase in patents related to combination therapies and bioavailability enhancers.
Key competitors:
- Local firms like "Pharmstandart" and "Petrovax."
- Foreign firms registering extensions and variations via the Eurasian Patent Office.
The landscape indicates a crowded environment where incremental innovations are protected through narrow claims, making patent landscape navigation complex for new entrants.
Critical considerations for patent infringement and freedom-to-operate
- The patent’s claims focus on specific compositions and synthesis, reducing risk of infringement by using different ratios or active compounds.
- Any deviation from the detailed preparation method specified could avoid infringement.
- The scope appears limited within Russia; international protection may require additional filings for broader coverage.
Key legal and strategic points
- Patent validity is supported by prior art analysis, with no direct prior art invalidating claims.
- The patent is enforceable within Russia for 20 years from the priority date.
- Strategic extensions or supplementary patents could be pursued, especially around formulation optimizations.
Summary
Patent RU2020113888 protects a specific pharmacological formulation involving defined active compounds, with claims focused on particular compositions and methods. Its scope is narrow, primarily covering specific embodiments rather than broad chemical classes. The Russian patent landscape for related drugs is competitive with many incremental innovations and filings. Achieving freedom-to-operate would depend on identifying non-infringing formulations or methods differing from the claimed invention.
Key Takeaways
- The patent covers a targeted pharmaceutical composition with defined ratios and production methods.
- Its claims are narrow, reducing infringement risk but limiting market exclusivity.
- The Russian patent landscape favors incremental innovations, making broad patenting challenging.
- For international markets, filing in jurisdictions such as Eurasia or Europe might be necessary.
- Monitoring competitors' filings around similar APIs or formulations remains critical.
FAQs
1. How broad are the claims in patent RU2020113888?
The claims are specific to certain chemical compositions and preparation methods, limiting their scope to particular embodiments rather than broad chemical classes.
2. Can the patent be challenged based on prior art?
Yes, if prior art discloses similar compositions or methods with earlier dates, the patent could face validity challenges.
3. Does this patent provide protection outside Russia?
No, Russia-specific patents do not automatically extend protection to other markets; separate filings are required.
4. How does this patent impact generic drug development?
It narrows the scope for generic equivalents, especially if they use different active compounds or formulations, but does not block entirely.
5. What are the strategic considerations for companies targeting this patent?
They should focus on designing around these claims by altering formulations, active ingredients, or manufacturing methods to avoid infringement.
