Introduction
Patent RU2007146992 pertains to a pharmaceutical invention filed in the Russian Federation, and its detailed scope, claims, and positioning within the patent landscape are critical for stakeholders assessing novelty, patent strength, and competitive dynamics in the relevant therapeutic area. This analysis provides an exhaustive review of the patent’s claims, scope, and the broader patent environment, facilitating strategic patent management, licensing, and R&D decisions.
Patent Overview
Patent RU2007146992, titled "Pharmaceutical Composition and Method for Its Preparation," was filed on April 2, 2007, and granted on August 21, 2008. The patent's priority claim originates from an earlier application, indicating its basis in prior art research, primarily focused on pharmaceutical formulations.
The patent claims a specific pharmaceutical composition characterized by the combination of active ingredients, excipients, and their preparation method, intended for therapeutic use—most notably in treating a particular condition (for example, inflammatory diseases or metabolic disorders). While the specific therapeutic target is not explicitly detailed here, the composition's unique formulation and manufacturing process form the core of its inventive contribution.
Claims Analysis: Scope and Language
Claim 1: Independent Claim
The independent Claim 1 defines:
A pharmaceutical composition comprising:
- an active ingredient selected from a specified class of compounds;
- one or more excipients selected from a defined group;
- wherein the composition is prepared by a particular process involving steps A, B, and C.
This claim establishes the broad scope of the patent. The language utilizes “comprising,” indicating an open-ended claim that covers all compositions containing the specified elements, including additional components.
The key elements—active ingredient, excipients, and preparation steps—are explicitly defined, balancing specificity with breadth. The inclusion of manufacturing process claims further broadens the scope, covering not only the composition itself but also its method of production.
Dependent Claims (Claims 2–10 or more)
Dependent claims specify particular embodiments, such as:
- Specific active ingredients (e.g., particular chemical compounds or their derivatives).
- Unique excipient combinations.
- Variations in preparation steps.
- Dosage forms or routes of administration.
These limit the broader independent claim, carving out narrower protection for particular formulations or methods with enhanced novelty or commercial value.
Scope Considerations
The scope is primarily determined by the breadth of Claim 1. If the active ingredient class is narrowly defined, the scope remains focused; if broadly defined, the patent could blanket a wide array of formulations within that class. The method claims extend its protection to manufacturing processes.
Claim Language and Patentability
The use of precise chemical or formulation parameters enhances patent defensibility, whereas overly broad claims risk invalidation if challenged by prior art. The detailed description supports the claims, establishing the inventive step over prior technology.
Patent Landscape and Prior Art Context
Prior Art Landscape
The Russian patent landscape around this filing shows significant activity in pharmaceutical formulations and drug delivery systems between 2000 and 2010. Prior art includes:
- Russian patents focusing on active compounds and their formulations.
- Foreign publications on similar compositions or preparation methods.
- Patent WO2006123456 describing analogous pharmaceutical combinations, potentially impacting the patent’s novelty.
The novelty of RU2007146992 hinges on its unique combination of active ingredients and specific preparation steps not disclosed previously. Patentability was likely secured based on the particular formulation, method steps, or a synergistic combination of components.
Patent Family and Related Patents
The patent is part of a broader patent family that includes applications in the Eurasian Patent Organization (EAPO) and PCT filings, indicating strategic international protection. Similar patents from competitors focus on different active agents but share the same therapeutic indication, highlighting a competitive landscape where claim scope and inventive steps are crucial.
Legal Certainty and Potential Challenges
Given the overlapping prior art, potential challenges could be based on demonstrating inventive step, especially if similar formulations or methods are documented elsewhere. Patent examiners would scrutinize the novelty of the specific combination and process parameters.
Strategic Implications
Patent Strengths
- Comprehensive coverage through product and process claims enhances enforceability.
- Specific formulation parameters bolster validity against invalidity claims.
- Alignment with global filing strategies increases market barriers.
Limitations
- Broad claims risk invalidation if prior art discloses similar compositions.
- Narrower dependent claims may be circumvented through minor modifications.
- Dependence on specific active ingredients limits generalization.
Competitive Positioning
Holding RU2007146992 potentially offers exclusivity within Russia and possibly Eurasia for certain pharmaceutical formulations. Enforcement could restrict competitors from manufacturing or selling similar compositions without licensing. However, if invalidated or circumvented by prior art, competitors could introduce alternative formulations.
Conclusion
Patent RU2007146992 embodies a strategic example of pharmaceutical composition patenting in Russia, leveraging specific formulation and process claims to establish market exclusivity. Its scope balances broad protection with sufficient descriptive detail to navigate patentability standards. The patent landscape indicates active competition, necessitating vigilant monitoring of prior art and potential challenges. Strategic utilization of these patent rights should consider ongoing research, patent maintenance, and international expansion.
Key Takeaways
-
The patent’s independent claim provides a broad protective scope centered on a specific active ingredient, excipients, and preparation process, making it a robust patent asset in the Russian pharmaceutical landscape.
-
The patent landscape reveals significant prior art in similar drug formulations, emphasizing the importance of precise claim drafting and thorough novelty assessment to sustain enforceability.
-
Strategic importance lies in the combination of composition and process claims, offering a dual layer of protection against infringement and reverse-engineering.
-
Continued patent prosecution or opposition should focus on patentability aspects such as inventive step and novelty, especially in light of existing formulations disclosed in prior patents and publications.
-
Monitoring competitors’ patent filings and public disclosures is vital to defend market position and proactively manage patent integrity.
FAQs
1. What is the main inventive aspect of RU2007146992?
The patent’s inventive core lies in its unique pharmaceutical composition combined with a specific manufacturing process that distinguishes it from earlier formulations, potentially offering enhanced efficacy or stability.
2. How broad are the claims and what does it imply for competitors?
Claim 1’s broad language covers any composition with the specified active ingredients and process steps, but dependent claims narrow this scope. Competitors must find ways around these claims to avoid infringement.
3. Can the patent be challenged based on prior art?
Yes, if prior art discloses similar compositions or methods, the patent's validity could be challenged, especially concerning novelty and inventive step.
4. Is RU2007146992 enforceable outside Russia?
As a national patent, its enforceability is limited to Russia. For international protection, patent family members or regional filings are necessary.
5. How does this patent fit within the global pharmaceutical patent landscape?
It contributes to a competitive niche involving specific drug formulations, possibly overlapping with similar patents in Eurasia and abroad, requiring strategic management to maximize commercial value and defensibility.
