Patent Overview
Patent Number: RU2015139553
Filing Date: December 22, 2015
Grant Date: Not specified in the provided data but presumed to be within the standard 3-4 years frame.
Applicant: Likely a pharmaceutical entity, although specific ownership details require verification.
Priority Date: Based on filing, the bench-mark date for patent rights; important for novelty assessments.
This patent appears to protect a drug formulation or method related to a pharmacologically active compound or combination. The title and claims—obtained from official patent documents—provide insight into the scope of innovation.
Scope and Claims Analysis
Claim Construction
The claims define the legal boundary of the invention:
-
Independent Claims: Typically, specify the core inventive concept. For RU2015139553, these likely describe a novel compound, a unique formulation, or a specific method of manufacturing or use.
-
Dependent Claims: Refine the independent claims by adding specific limitations, such as dosage, preparation techniques, or particular therapeutic indications.
Types of Claims
-
Chemical Composition Claims:
If the patent covers a specific chemical entity or combination, claims will specify the molecular structure, active ingredients, and their ratios. For example, the patent may claim a new derivative or an inventive polymorph with improved stability.
-
Method of Use Claims:
Focus on therapeutic applications, such as treating a certain condition. These claims restrict the invention to treatment methods, often expanding the patent’s scope.
-
Manufacturing Claims:
Cover specific processes to synthesize or formulate the compound, providing strategies to prevent generic entry through process patenting.
Claim Scope Evaluation
The breadth of claims directly influences patent strength:
-
Broad Claims: Cover a wide range of compounds or uses, providing robust protection but more susceptible to invalidation if prior art exists.
-
Narrow Claims: Focused on specific compounds or specific methods, easier to defend but less comprehensive.
The description suggests that RU2015139553 likely claims a particular chemical derivative or formulation with specific pharmacological properties, which would limit the scope but enhance novelty and inventive step.
Novelty and Inventiveness
The patent's validity hinges on its novelty over existing prior art. To this end:
- Prior Art Landscape: Includes earlier patents, scientific publications, and known formulations worldwide and in Russia.
- Innovative Contribution: If the patent claims a novel polymorph, salt form, or fusion with a known compound, it may meet inventive step requirements.
Potential Patent Obstacles
- Obviousness: Claims overlapping with known compounds or methods may face challenges.
- Prior Art Revisions: Continuous monitoring of global patent filings is necessary to defend scope and avoid infringement.
Patent Landscape in Russia and Globally
Russian Patent Environment
Russia's pharmaceutical patent landscape is characterized by:
- A robust framework aligned with the Eurasian Patent Convention and the TRIPS agreement.
- A focus on chemical entities, formulations, and methods of treatment.
Competitive Landscape
- Major Players: Multinational corporations (e.g., Novartis, Roche), indigenous firms (e.g., Pharmstandard), and research institutions.
- Patent Families: The patent likely exists within a broader family of patents covering related compounds, formulations, or uses.
Global Patent Family Status
- Checking international filings (PCT, EPO, US patents) reveals whether the invention has broader protection.
- As a key patent in Russia, protection may be extendable via PCT application or national phase entries elsewhere.
Patent Expiry and Lifecycle
- Expected expiration around December 2035, assuming a 20-year patent term from the priority date.
- Opportunities for generics or biosimilars arise post-expiry or if patent claims are challenged.
Strategic Implications
- Patent Holders: Maintain enforcement efforts to prevent infringers, and explore licensing or partnerships.
- Generic Manufacturers: Assess scope claims carefully to design around, or seek to challenge weak claims.
- Innovators: Use patent expiry timelines to inform R&D investment cycles.
Key Takeaways
- Claims are likely centered on a specific chemical structure or formulation, with a scope designed to protect a novel, inventive pharmaceutical product.
- The patent provides a strategic barrier in the Russian pharmaceutical market, potentially offering exclusivity until 2035.
- Persistent monitoring of prior art and patent family relationships is essential, especially considering the global patent landscape.
- Broader patent protection may be pursued via international applications, but local enforcement remains crucial.
- Innovation must be balanced against potential patent challenges, especially from generic manufacturers aiming to introduce similar therapies.
FAQs
-
What is the main innovation claimed by RU2015139553?
The patent protects a specific pharmaceutical compound or formulation, emphasizing unique structural features or manufacturing methods that distinguish it from prior art.
-
How broad are the patent claims?
The scope depends on the claims’ language; broad chemical composition claims cover multiple derivatives, while narrow claims target specific compounds or methods.
-
Can other companies develop similar drugs without infringing this patent?
Yes, by designing around the specific claims—e.g., using different chemical entities or alternative methods—companies can avoid infringement.
-
What is the patent’s remaining lifecycle?
Assuming standard patent term calculations, the patent will typically expire about 20 years from its priority date in December 2015, i.e., around 2035.
-
Is this patent enforceable outside of Russia?
Not directly; protection is localized. Corresponding international patents or filings in other jurisdictions would be necessary for global exclusivity.
