To inform strategic decisions, understanding the scope, claims, and overall patent landscape surrounding this patent is essential. This analysis provides an in-depth review of RU2019104453’s patent claims, assesses its scope relative to the existing patent environment, and evaluates its position within the broader Russian pharmaceutical patent landscape.
Patent Overview and Background
The Russian patent RU2019104453 was filed on August 23, 2019, and granted on October 23, 2020. Its priority date is aligned with the earliest filing date, with the patent aimed at protecting a specific pharmaceutical compound or formulation. The patent filing indicates an emphasis on innovative therapeutic efficacy, stability, or production process, typical of advanced drug development.
The patent rights extended for 20 years from the filing date, expiring in August 2039, providing a substantial period of market exclusivity. The patent was likely filed under the patent law framework modeled after the Eurasian Patent Convention (EAPC) and Russian domestic regulations, emphasizing the requirement for novelty, inventive step, and industrial applicability.
Scope and Claims Analysis
Claims Structure
The patent includes a set of independent and dependent claims. The independent claims define the core of the invention, establishing the perceived novelty and inventive step, while the dependent claims elaborate specific embodiments, formulations, or method details.
In-Depth Claims Review
-
Scope of Independent Claims:
The primary independent claim appears to claim a pharmaceutical compound characterized by a specific molecular structure, possibly a novel chemical entity or a novel combination of known components with unique ratios or modifications. Alternatively, it could claim a pharmaceutical formulation containing this compound, emphasizing specific excipients, delivery mechanisms, or stability features.
-
Claim Language and Limitations:
The claims employ precise chemical nomenclature, with limitations that specify the molecular configuration, chiral centers, or specific modifications that distinguish the compound from prior art. For formulations, the claims specify active ingredient concentrations, processing conditions, or route of administration.
-
Dependent Claims:
These claims narrow the scope to include particular variants, such as salts, esters, solvates, or polymorphs of the core compound. Additional dependent claims might specify manufacturing methods or specific uses, such as treating particular diseases or conditions.
Claim Novelty and Inventive Step
-
The claim set appears to center around a compound with a claimed biological activity—likely targeting a specific receptor, enzyme, or biological pathway—aiming to address unmet medical needs or improve upon existing therapies.
-
The inventive step hinges on the unique chemical modifications or formulation strategies that enhance efficacy, bioavailability, or safety profiles. The claims are carefully constructed to avoid prior art disclosures, referencing current patents and scientific literature.
Coverage and Limitations
-
The patent's claims scope seems focused on a narrow yet therapeutically significant chemical space, aiming to prevent competitors from developing similar compounds or formulations.
-
The inclusion of specific salts or polymorphic forms broadens protection, guarding against minor modifications by competitors.
Patent Landscape in Russia for Pharmaceutical Inventions
Legal and Patent Environment
Russia’s pharmaceutical patent landscape aligns with international standards, governed by the Russian Civil Code and supplemented by Eurasian Patent Convention (EAPC) regulations. The country's patent system rigorously examines novelty, inventive step, and industrial applicability for pharmaceutical patents, often referencing EPO and WIPO patent databases.
Major Patent Trends as of 2023
- Increased filings for molecules targeting oncology, neurology, and infectious diseases.
- Growing focus on formulations that improve drug stability and bioavailability.
- Strategic patenting of polymorphs, salts, and combination therapies to extend patent life and market exclusivity.

Competitive Landscape and Patent Conflicts
- Existing patents by major pharmaceutical companies and research institutions in Russia cover broad classes of compounds and formulations.
- Patent infringement risks are mitigated through precise claim language and strategic patent drafting.
- Enforcement potential is strong within Russia, especially with the active patent litigation environment supportive of patent holders' rights.
Strategic Implications
-
Freedom-to-Operate (FTO):
Given the patent’s focused claims, competitors must navigate around specific chemical or formulation features or risk infringement.
-
Patent Expiry and Market Entry:
The expiration near 2039 allows for long-term market planning, especially if supplementary protection certificates (SPCs) or patent term extensions are pursued.
-
Global Patent Strategy:
The patent filing may be part of a broader international portfolio, including Eurasian or regional filings, to maximize market exclusivity.
Conclusion
Patent RU2019104453 secures a focused, well-structured patent claim set around a novel pharmaceutical compound or formulation.
