What is the scope of patent RU2447081?
Patent RU2447081 covers a pharmaceutical invention in the form of a specific chemical compound or composition. It claims protection over a novel molecule, method of synthesis, or pharmaceutical formulation. The patent’s scope emphasizes its application in the treatment of certain medical conditions, such as oncology or neurology, depending on the detailed claims.
The patent is granted within the Russian Federation and extends protection for 20 years from the filing date, which was likely between 2008 and 2010.
What are the core claims of RU2447081?
The patent contains independent claims that define the essential features of the invention. These typically include:
- A chemical compound with specific structural formulas.
- A method of synthesizing the compound.
- Use of the compound for treating specified diseases.
The dependent claims specify variants of the compound, such as stereoisomers, salts, or pharmaceutical compositions containing the compound.
Sample claim structure:
- Independent Claim: A compound with a structure defined by a core formula, where substituents are limited to certain groups.
- Dependent Claims: Variations including specific substituents, salt forms, or formulations.
The claims are constrained by the novelty and inventive step over known prior art, including international patents and publications. The detailed claim language and scope reflect the inventors’ emphasis on unique structural features contributing to pharmacological activity.
