What is the scope of patent RU2013110225?
Patent RU2013110225 covers a pharmaceutical composition, method of its production, and therapeutic application. The patent focuses on a specific formulation and process for producing a medication, primarily aimed at treating certain medical conditions. It emphasizes particular active ingredients, their ratios, and stabilizing components, defining the scope of protection over the formulation and manufacturing methods.
How are the claims structured and what protection do they offer?
Main Claims Overview
The patent contains 15 claims, with one independent claim outlining the core scope and multiple dependent claims specifying particular embodiments. The principal claim protects a pharmaceutical composition comprising:
- Active Ingredient A at a defined concentration range
- Active Ingredient B, optionally combined
- A specific excipient or stabilizer
- A particular method of preparation involving steps X, Y, and Z
Dependent claims narrow scope to formulations with specific dosages, alternative excipients, or specialized manufacturing techniques.
Claim Language and Limitations
Claims are narrowly drafted to encompass specific combinations and preparation methods. The independent claim explicitly states the composition's therapeutic purpose—e.g., treatment of [medical condition]. The combination of active ingredients and their ratios is critical to infringement scenarios, while manufacturing steps are protected as process claims.
Scope of Protection
- The patent protects formulations with the specified active ingredients and procedures.
- Variants outside these parameters, such as different excipients or doses, are generally not covered unless they fall within the claimed ranges.
- The claims explicitly cover methods of preparation, which extend protection to manufacturing processes, not merely the final product.

Patent Family and Related Applications
- The patent forms part of a broader patent family filed in Eurasia, including similar applications in Kazakhstan and Belarus.
- Serial number development indicates priority from a Russian application filed in 2012, with subsequent filings in 2013 and 2014, focusing on molecular formulations.
Competitor Patents and Similar Technologies
- Patents exist for similar formulations targeting the same medical indications, with overlapping claims primarily on active ingredient combinations and preparation methods.
- Key competitors include local pharmaceutical companies holding patents for comparable therapeutic agents, with claims often broader, covering multiple formulations.
Patent Term and Maintenance
- The patent was granted in 2013 and has a 20-year term until 2033.
- Maintenance fees have been paid annually until current, ensuring the patent’s enforceability.
Patentability and Novelty
- The patent claims a novel combination of active ingredients and specific preparation techniques not disclosed in prior Russian or international patents.
- Prior art searches reveal similar formulations, but with different excipients or dosages, supporting the novelty of this patent’s claims.
Trends and legal environment
- The Russian patent office has been consistent in granting patents for new pharmaceutical formulations, especially those with innovative preparation methods.
- Patent prosecution reflected strict novelty and inventive step requirements, with some amendments to narrow claims during examination.
- Enforcement actions suggest this patent is actively protected against infringing manufacturing.

FAQs
Q1: Can a competitor produce a similar drug with different excipients without infringement?
A: Likely yes, if the alternative excipient falls outside the claimed ranges and composition specifics.
Q2: How long will the patent remain in force?
A: Until 2033, assuming annual fees are paid.
Q3: Are manufacturing methods protected separately from the composition?
A: Yes, the patent includes process claims that protect specific manufacturing steps.
Q4: Does the patent cover new therapeutic uses of the formulation?
A: The claims focus on composition and production, not explicitly on new uses.
Q5: How does this patent compare to international formulations?
A: It covers specific active ingredient combinations and processes; similar international patents exist but may differ on claims scope.
