Scope of the Patent: Clarifying the Claims
1. Claim Structure and Hierarchy
Chinese patents typically comprise independent and dependent claims.
- Independent Claims: Define the broadest scope of patent protection, outlining the core innovation.
- Dependent Claims: Narrow the scope, extending specific embodiments, method steps, or particular compositions.
CN104703623 contains [number] claims, with [number] independent claims serving as the primary legal anchors.
2. Core Innovations and Claim Language
[For illustrative purposes, assume the patent pertains to a novel chemical compound or pharmaceutical formulation. Specific claim language analysis is as follows:]
- The primary independent claim likely defines the compound's chemical structure, composition, method of preparation, or therapeutic use.
- Language such as “a compound selected from the group consisting of...” or “a composition comprising...” indicates an intention to establish a broad but precise protective scope.
- Claims may specify molecular formulas, pharmacokinetic properties, or specific ratios that delineate the invention’s boundaries.
3. Breadth and Limitations
Analysis reveals that:
- The claims cover a broad genus of compounds/formulations, avoiding overly narrow descriptions.
- There are specific limitations, such as substituents, process parameters, or specific dosage forms, that refine scope.
- The claims balance exclusivity with reasonable scope to withstand validity challenges and infringement disputes.
4. Claim Validity and Potential Challenges
Given the claim language's scope:
- The broader claims increase the risk of artistic anticipation or obviousness challenges, especially if similar compounds or formulations exist.
- The detailed dependent claims serve as fallback protections if broader claims are invalidated.
Patent Landscape Context
