The patent's content is accessible via Rospatent's database, indicating that it claims an inventive step that differentiates it from prior art in the Russian pharmaceutical landscape.
Scope of the Patent
Legal Scope
The scope of RU2429882 primarily depends on the claims section, which delineates the boundaries of the patent’s exclusivity. The claims are crafted to protect:
- The chemical compound or composition itself
- Methods of synthesis or preparation
- Therapeutic uses and treatment methods
Claims are categorized as:
- Independent claims, establishing the core invention;
- Dependent claims, elaborating on particular embodiments or specific variants.
The patent explicitly claims a specific chemical structure or molecule, possibly with pharmacological activity. It might also include formulations optimized for stability or bioavailability, and methods of treatment involving the compound.
Scope of Protection
The patent likely aims for broad protection, covering various derivatives or formulations within its chemical class, and potentially encompassing multiple therapeutic indications.
However, the scope can be limited by the linguistic framing of claims. For instance, Markush groups—a common claim type in chemical patents—may list multiple variants, broadening protection. Conversely, narrower claims, if present, could limit protection to particular compounds or uses.
Limitations and Exclusions
Restrictions may exist where claims avoid unpatentable subject matter or are limited by prior art. For example, if the invention involves known chemical groups or methods, claims may be tailored to specific novel arrangements.
Analysis of the Claims
Key Features of the Claims
1. Independent Claim(s):
Typically define the core compound or method with specific structural features or steps. Example:
“A compound of formula (I), characterized by X, Y, Z groups, or a pharmaceutically acceptable salt or ester thereof.”
2. Dependent Claims:
Refine or specify particular embodiments, such as:
- Specific substituents or functional groups
- Particular formulations (e.g., tablets, injections)
- Use in specific disease indications
3. Method Claims:
Describe therapeutic methods, e.g., administering a defined dose of the compound to treat a specific disease.
Breadth and Novelty
The breadth of the claims determines the patent’s strategic strength. Broad claims that encompass numerous derivatives offer extensive protection but are more vulnerable to invalidation if prior art contains similar compounds.
Novelty is rooted in the chemical structure or application. Claim language must clearly distinguish the invention from prior art to withstand legal challenges. The patent likely cites references to prior art that it overcomes through inventive features, such as unique substitutions or unexpected pharmacological effects.
Potential Clarity and Support Issues
In Russian patent law, clarity and sufficient disclosure are mandatory. If claims or description are ambiguous, they risk being invalidated. The patent probably includes detailed descriptions and examples to substantiate the claims' scope.
