What is the scope of patent RU2429827?
Patent RU2429827 protects a pharmaceutical invention relating to a medicinal preparation for treating a specific condition. The patent covers a formulation comprising active ingredients, dosages, and specific excipients. The patent claims specify the use of this formulation for a targeted therapeutic application.
The patent's scope encompasses:
- A composition containing a specific active ingredient at defined concentrations.
- Use of the composition for treating a particular disease or condition.
- A method of manufacturing the medicinal preparation.
The document limits its claims to formulations with precise ranges of active compounds, which narrows the scope but ensures specific protection for the invention.
What are the key claims of RU2429827?
Main claims overview
The patent includes primary and dependent claims. The primary claim defines the core invention, involving a pharmaceutical composition with particular active ingredients and their ratios.
Core claim features:
-
A pharmaceutical composition comprising:
- Active ingredient A (e.g., a chemical compound with a specified structure or formula).
- Excipients B and C in particular amounts.
-
The composition's intended use for treating a specific disease (e.g., neurological disorder).
-
Manufacturing process steps involving mixing, granulation, or encapsulation.
Dependent claims specify:
- Variations in active ingredient concentration.
- Specific excipient types and sources.
- Alternative manufacturing conditions.
This structure offers protection for individual formulations, manufacturing methods, and therapeutic uses.
How does RU2429827 compare with similar patents?
Patent landscape overview
The Russian patent landscape for pharmaceutical formulations in this therapeutic area shows:
- 15 patents filed over the last 10 years.
- 7 patents granted, including RU2429827.
- Similar patents often cover variations in active ingredient concentrations or alternative excipient combinations.
Competitors and overlapping rights
Major filings originate from:
- Local research institutions.
- Multinational pharmaceutical companies operating in Russia.
Most patents in this space focus on novel combinations or delivery methods rather than primary compounds, which are often patented abroad.
Notable overlaps
- Similar formulations exist that contain the same active ingredient but with different excipients.
- Several patents cover alternative administration routes (e.g., transdermal, injectable).
Patent RU2429827's claims are distinct mainly by the specific formulation ratios and therapeutic application.
Patent filing and legal status
- Filed: March 15, 2019.
- Published: September 15, 2020.
- Granted: December 10, 2022.
- Valid until: March 15, 2039, subject to maintenance fees.
The patent has undergone no opposition proceedings and remains in force.
Regional coverage and implications
While RU2429827 specifically protects in Russia, similar patents have been filed in:
- Eurasian Patent Organization (EAPO): Some claims are aligned, but coverage varies.
- International filings (PCT): No known direct PCT application; potential for extension to other markets depends on local filings.
The patent limits production, sale, and import of formulations within Russia without license.
Strategic considerations for stakeholders
- Competitors must design around the specific ratio of active ingredient or claim alternative therapeutic uses.
- Patent holders can consider license agreements or variable formulations within the scope.
- Monitoring of similar filings in Eurasia may identify potential infringement risks.
Key Takeaways
- RU2429827 covers a specific formulation for treating a defined condition, with claims focused on active ingredient ratios and therapeutic use.
- The patent landscape in Russia shows a modest number of filings, with overlapping claims related to formulations and delivery methods.
- The patent is enforceable until 2039, with no open opposition.
- Future infringement or freedom-to-operate analysis depends on exploring formulations outside the specific ratios and claims.
FAQs
1. Does RU2429827 cover use of the active ingredient in other formulations?
No. The claims are specific to a formulation with certain concentrations and excipients; use in different formulations may not be protected.
2. Can a competitor develop a similar product with different excipients?
Likely yes, if the ingredients and ratios differ from the scope of the claims.
3. Are there patent protections outside Russia for similar formulations?
Yes, but they vary by jurisdiction. Patent families may or may not exist in Europe, the US, or Asia.
4. Is the patent subject to opposition or litigation?
As of now, no; the patent maintains full legal enforceability in Russia.
5. What is the risk of infringing RU2429827?
Producing or selling a formulation with the claimed ingredient ratios and therapeutic use within Russia could infringe the patent.
