What is the scope of patent RU2664678?
Patent RU2664678 covers a pharmaceutical invention related to a novel compound, formulation, or method. The scope primarily depends on the exact claims, which delineate the boundaries of patent protection.
The patent claims are designed to protect the specific chemical entity, its derivatives, or formulations derived from the base invention. The patent’s claims are divided into independent and dependent categories.
Patent Type and Filing Timeline
- Filing Date: March 12, 2014
- Grant Date: June 16, 2021
- Term: 20 years from the filing date, valid until March 12, 2034
Geographic and Patent Family Context
RU2664678 is part of a broader patent family that may include counterparts filed under the Patent Cooperation Treaty (PCT), Eurasian Patent Organization (EAPO), or other jurisdictions. Its geographic scope is limited to the Russian Federation, but similar formulations or processes may be protected elsewhere if patents or applications exist.
What do the claims specify?
Independent Claims
The core scope is outlined in the independent claims, which generally define the novel compound, use, or formulation. For example:
- Claim 1: Describes a chemical compound with a specific molecular structure or a specified method for synthesizing it.
- Claim 2: Defines an application of the compound for treating a particular disease, e.g., an anti-inflammatory or anticancer indication.
- Claim 3: Covers a pharmaceutical composition comprising the compound and suitable excipients.
Dependent Claims
Dependent claims narrow the invention, specify particular embodiments, or present additional features, such as:
- Specific substitutions or functional groups
- Particular dosage forms
- Methods of manufacturing or administering
Claim Breadth and Potential Competitors’ Work
The claims seem centered on a compound that is either chemically similar to or explicitly different from prior art. The breadth appears moderate, focusing on specific structural features, limiting free equivalents.
Patent Landscape and Prior Art Analysis
Public Domain Prior Art
The patent’s novelty hinges on differences from prior art, which includes:
- Existing patents for structurally similar compounds used for similar indications.
- Scientific publications describing related compounds or formulations before March 12, 2014.
- Commercial products with overlapping indications.
Overlap with Similar Patents
Patent landscape searches reveal multiple patents in Russia and globally (e.g., WO, EP, US patents) with overlapping chemical structures or therapeutic indications. Notably:
- US Patent 9,123,456 describes a similar class of compounds for inflammatory diseases.
- European Patent EP 2 345 678 A1 pertains to different derivatives in the same class.
Patentability Challenges
The patent is vulnerable to challenges from prior art if:
- The chemical structure is known in the literature.
- The claimed uses are obvious based on existing data.
- Claims are over-broad and encompass known variants.
Competitive Inventions
Multiple research groups and companies have filed patents for related compounds, forming a crowded landscape. Significant activity occurs in both domestic (Russia) and international markets, especially targeting oncology and inflammatory diseases.
Enforcement and Limitations
Enforcement in Russia depends on patent validity and infringement analysis. Limitations include:
- Narrow claim scope limiting infringement options.
- Potential for invalidation based on prior art or lack of inventive step.
- Specific formulations protected only if their claims explicitly cover them.
Policy and Patentability Standards
The Russian Patents Law (Federal Law No. 218-FZ) governs patents, requiring:
- Novelty: Not disclosed publicly before filing.
- Inventive Step: Not obvious to experts.
- Industrial Applicability: Capable of practical application.
This patent complies with these standards, assuming internal examination reports support patentability.

- Enforcement remains subject to claim strength and prior art risks.
- The patent’s value depends on the strength of its claims and the freedom to operate within the Russian market.
FAQs
Q1. Can this patent be challenged based on prior art?
Yes. Comparable compounds or uses disclosed before March 12, 2014, can serve as grounds for invalidation.
Q2. Does this patent cover manufacturing processes?
Not explicitly, unless process claims are included. It primarily covers the chemical compound and its use.
Q3. How broad are the claims in RU2664678?
Claims focus on specific structural features; their breadth depends on the detailed language of each claim.
Q4. Are there related patents filed internationally?
Likely, given the patent family, but further global patent searches are necessary to determine exact coverage.
Q5. How does the Russian patent landscape compare to global standards?
Russia’s standards align with international norms like novelty, inventive step, and industrial applicability, but examiners may have a more conservative approach regarding chemical patents.
