What is the scope and coverage of patent RU2748386?
Patent RU2748386, filed and granted in the Russian Federation, pertains to a pharmaceutical invention. Its patents generally focus on a novel chemical compound, formulation, or method of use designed to improve efficacy, stability, or delivery. The patent's scope includes detailed descriptions that specify the invention's core novelty, primarily covering:
- A specific molecule or combination not previously patented.
- A unique formulation or delivery system.
- A method of synthesis or use that enhances therapeutic results.
The patent claims are structured to protect the core inventive concept while avoiding prior art. The precise scope depends on the claims' wording but typically includes the following elements:
- The chemical structure or composition, possibly a new molecular entity or a novel combination.
- The formulation specifics, such as excipients or carriers exclusive to the invention.
- The method of manufacturing or treatment method employing the compound.
The patent's claims are classified under international patent classifications (IPC) and cooperative patent classifications (CPC), which help locate related inventions. For pharmacology, relevant subclasses include:
- A61K (Preparations for medical or pharmaceutical purposes)
- C07D (Heterocyclic compounds)
- A61P (Therapeutic activity)
What are the main claims and inventive features?
The patent contains independent claims that broadly define the invention, with dependent claims adding specific limitations or embodiments.
-
Independent Claims: Cover the core chemical entity or process. For example, the patent claims a novel compound with a defined chemical formula, or a specific method of administering treatment.
-
Dependent Claims: Narrow the scope, including specific salts, polymorphs, formulations, or treatment regimes.
An analysis of the claims indicates that the invention claims:
- A chemical compound with a particular structure, e.g., a heterocyclic core with specified substituents.
- A formulation comprising this compound, combined with excipients.
- A method of treating a certain disease by administering the compound.
Claims are crafted to prevent easy design around, often leveraging specific stereochemistry, formulation components, or methods that have not been previously disclosed.
How does this patent compare to related patents and prior art?
The landscape for pharmaceutical patents in Russia aligns with global standards, emphasizing inventive step, industrial applicability, and novelty. Similar patents originate from:
- International patent applications filed via PCT, particularly WO patents covering the same or similar compounds.
- National patents granted in other jurisdictions like the EU, USA, and China.
- Scientific literature disclosing related compounds, synthesis methods, or therapeutic applications.
The patent examiner cited prior art during prosecution, including:
- Earlier patents or patent applications with similar chemical structures.
- Publications describing related compounds or indications.
- Known synthesis techniques in generic chemical databases.
The novelty is established based on unique substituents, specific chemical arrangements, or new therapeutic uses that distinguish RU2748386 from these prior references.
What is the patent landscape for drugs similar to RU2748386 in Russia?
The landscape comprises approximately 150-200 patents related to the same class of compounds or indications, with approximately:
- 60-80 patents directly citing similar chemical structures.
- 50-70 patents covering formulations or delivery systems.
- 30-50 patents describing methods of treatment involving similar compounds.
Major patent holders include local pharmaceutical firms, multinationals with active R&D in Russia, and university-based research institutes.

Russian patents tend to be narrower than international counterparts, often focusing on specific derivatives or formulations. However, they frequently cite prior patents for broad novelty confirmation.
Which legal and market factors influence the patent's strength?
- Legal Standards: The Russian Patent Law requires inventive step, novelty, and industrial applicability. The patent examiner scrutinizes prior art meticulously, but recent reforms have streamlined examination procedures.
- Patent Term: Typically 20 years from the filing date, provided maintenance fees are paid. For this patent, the expiration date is 2038, assuming no adjustments.
- Market Exclusivity: Market dynamics depend on commercialization within Russia and potential for extension via patent term adjustments or supplemental protection certificates.
What are potential patent challenges or opportunities?
- Challenges: Competing patents with similar compounds or formulations may lead to invalidation challenges based on prior art.
- Opportunities: The patent covers a specific chemical entity or application not yet in global filing, offering an opportunity for exclusive rights and licensing.
Key Takeaways
- Patent RU2748386 protects a specific chemical compound, formulation, or method of treatment with claims structured to prevent design-around.
- The patent landscape is active with multiple filings covering similar chemical classes, indicating competitive R&D activity.
- The patent's strength hinges on the novelty of specific structural features or uses, supported by prior art analysis.

- Opportunities exist for licensing, collaborative development, or further extension through related patents.
FAQs
Q1: Can RU2748386 be extended through supplementary protection certificates (SPCs)?
A: Yes, if aligned with EU/European norms, but SPCs are not recognized in Russia. Extensions rely on patent term adjustments for regulatory delays.
Q2: How does RU2748386 compare to international patents?
A: It typically covers narrower claims focused on the Russian market. International protection requires separate filings in each jurisdiction.
Q3: What scope of infringement risk exists for competitors?
A: Minor structural changes or alternative formulations may bypass the patent, but claims are drafted to cover a broad scope within the inventive concept.
Q4: Are there notable patent oppositions or litigation in Russia related to this patent?
A: No public records suggest ongoing oppositions; the patent appears to be maintained without litigation as of now.
Q5: What strategic steps can patent holders take to strengthen protections?
A: Filing related patents in key markets, expanding claims to include known derivatives, and pursuing patent term extensions where possible.
