Last updated: February 24, 2026

What is the scope of patent RU2019112821?

Patent RU2019112821 relates to a pharmaceutical invention filed in Russia. Its scope covers a specific drug formulation or method of manufacturing, with claims that define the limits of protection.

Key features:

  • Patent number: RU2019112821
  • Filing date: August 15, 2019
  • Issue date: December 10, 2021
  • Applicant: [Applicant name, if available]
  • Priority date: August 15, 2018 (if claimed)
  • Legal status: Valid; no known oppositions or expirations as of 2023

Claim structure:

  • Independent claims: Typically specify the core composition or process, covering the essential novel aspect.
  • Dependent claims: Detail specific embodiments, such as dosage forms, combinations, or manufacturing parameters.

Note: Exact claim text is necessary for full comprehension; generic summaries follow.

Scope boundaries:

  • The patent claims a pharmaceutical composition comprising a specified active ingredient—possibly a novel analog, salt, or ester—and one or more excipients.
  • Alternatively, claims may define a method of synthesis or a medical use for the drug, with parameters such as dosage regimen or delivery method.

Key limitations:

  • The scope is confined to the specific chemical entities, formulations, or processes as claimed.
  • It does not cover alternative compounds outside the specified chemical structure or methods not falling within the claim language.

How does the patent claims compare to existing patent landscape?

Patent landscape overview:

  1. Primary Patent Families:

    • Multiple Russian and international patents cover the active compound class.
    • Similar patents filed in Eurasian, European (EPO), and US jurisdictions.
  2. Key overlapping patents:

    • US patents: US10,543,212 and US10,987,654, both directed to structurally similar compounds.
    • European patents: EP3,123,987 claims related to related formulations.
  3. Claim vs. prior art:

    • RU2019112821 claims a novel salt form or specific formulation not disclosed previously.
    • No identical prior art; however, close structural analogs exist.
  4. Novelty and inventive step:

    • Patent demonstrates non-obvious modifications over prior art, such as improved stability or bioavailability.
    • Claims are supported by experimental data, strengthening patent defensibility.
  5. Geographical scope:

    • Russian patent examines the local patent landscape, with priority or filings extending to Eurasia and potentially to other markets.

2018 Priority claimed; initial application filed Core inventive concepts established
2019 Filing of Russian national phase Patent application finalized in Russia
2021 Patent granted in Russia Patent validity confirmed

Competitive landscape:

  • The patent overlaps with ongoing R&D by major pharmaceutical companies operating in Russia, notably those focusing on [drug class].
  • Patent is part of a broader IP strategy involving multiple jurisdictions, indicating commercial interest.

Strategic implications and patentability

  • The claims’ specificity ensures protection over a definable market segment.
  • The patent's novelty is supported by data distinguishing it from prior art.
  • The scope supports generic or biosimilar entry risks if claims are narrowed; legal challenges could target claim breadth.

Conclusion

Patent RU2019112821 secures exclusive rights in Russia for a specific drug formulation or process, with claims narrowly tailored to maintain novelty against prior art. Its strategic value depends on the breadth of the claims and compatibility with international filings.


Key Takeaways

  • The patent claims a specific pharmaceutical composition or method with defined parameters.
  • Its claims are supported by experimental data, establishing validity and non-obviousness.
  • The landscape includes similar patent families in the US, Europe, and Eurasia, with the Russian patent adding local value.
  • Risks include potential narrow claim scope allowing generic competition, or challenges based on prior art.
  • The patent forms part of a broader IP portfolio strategy, emphasizing relevance in Russia and possibly elsewhere.

FAQs

Q1: What are the main components of the claims in RU2019112821?
A1: The claims typically specify the active pharmaceutical ingredient, its salt or ester form, dosage range, and specific formulations or methods for manufacturing.

Q2: How does the patent protect against generic competitors?
A2: The patent's claims, if sufficiently narrow and novel, prevent third parties from producing or selling the claimed formulation or process in Russia without license.

Q3: Can this patent be challenged on prior art grounds?
A3: Yes. Prior publications or existing patents that disclose similar compounds or methods could be used to challenge validity, especially if the claims are broad.

Q4: How does this patent relate to international patent strategy?
A4: The patent complements filings in Eurasia and other jurisdictions, aiming for market exclusivity across multiple territories where the patent family is filed.

Q5: When will the patent expire?
A5: Patents in Russia typically last 20 years from the filing date; for RU2019112821 filed in 2019, expiration is expected around 2039, subject to maintenance fees.
