CN113354649 appears to cover [specific compounds, methods, or formulations, e.g., a novel small molecule inhibitor, a pharmaceutical composition or a specific method of synthesis].
The patent's claims are structured to delineate inventive features that distinguish it from prior art, targeting [core innovation, e.g., enhanced bioavailability, reduced toxicity, or novel therapeutic efficacy]. This scope potentially restricts competitors from developing similar formulations or methods, thus establishing a strong position within its product category.
Biological and Chemical Scope
If the patent claims involve a chemical compound, the scope may include:
- The core compound comprising [specific chemical structure or class]
- Derivatives, salts, or prodrugs of the core compound
- Related formulations or delivery systems
For method-based claims, the scope could extend to:
- Specific synthesis pathways
- Treatment protocols utilizing the compound
- Diagnostic or biomarker selection methods
Parameter and Limitation Controls
The claims likely specify critical parameters—such as dosage, concentration, or biological markers—which refine the scope and eligibility for potential patent challenges or licensing.
Claims Analysis
Claim Structure and Hierarchy
Patent CN113354649 probably contains a set of claims categorized into:
- Independent Claims: Broadest protective provisions, often encompassing the core invention.
- Dependent Claims: Narrower claims that specify particular embodiments, additional features, or specific implementations.
Key Claim Features
-
Chemical Structure Claims: If the patent targets a chemical entity, the independent claim might define the molecular formula, substituents, or stereochemistry, e.g., “A compound represented by structure X, wherein R1 to Rn are defined as...”.
-
Method Claims: Could cover manufacturing processes, experimental treatment procedures, or diagnostic uses, e.g., “A method for treating [disease] involving administering a compound as defined in claim 1”.
-
Formulation Claims: Might specify particular combinations or delivery systems, such as liposomal, nanoparticle, or sustained-release formulations.
Claim Novelty and Inventive Step
The novelty hinges on distinguishing features absent in prior art, such as unique structural modifications, synthesis routes, or therapeutic effects. The inventive step likely resides in [specific advantage, e.g., increased efficacy, reduced toxicity, novel mechanism of action].
Potential Overlaps and Challenges
Stakeholders must consider prior art in the same therapeutic domain, including patents from [owning companies or research institutions], to prevent infringement risks. In China, the scope's robustness depends on how well the claims differentiate from existing patents, especially in rapidly evolving fields like biotech.
