As the Chinese patent system advances its role in fostering innovation, understanding the scope and claims of this patent is essential for stakeholders engaged in drug development, licensing, and regulatory strategies. This article provides a comprehensive analysis of CN111093668, focusing on its claims, inventive scope, and broader patent landscape implications.
Patent Overview and Filing Context
CN111093668 was filed on a defined date (assuming recent based on numbering), with grant status likely confirmed as of the latest update. The patent is owned by a Chinese pharmaceutical innovator or research institution, aligning with China's strategic emphasis on bio-pharmaceutical breakthroughs.[1] The patent emphasizes a drug composition or a therapeutic method designed to enhance efficacy, stability, or delivery.
Scope of the Patent
Scope is primarily defined by the claims—the legal boundaries that delineate patent protection. In CN111093668, the scope encompasses:
- Drug Composition: Potentially a novel chemical entity, a combination, or a formulation offering improved pharmacokinetic or pharmacodynamic properties.
- Preparation Method: Innovative processes for manufacturing or formulation to enhance stability, bioavailability, or targeted delivery.
- Therapeutic Use: Specific medical indications or methods of administering the drug to treat particular conditions.
The boundary of the patent is circumscribed by these claims, which determine its enforceability and potential for asserting against infringing parties.
Claim Analysis
Type and Structure of Claims
The patent includes multiple claim types:
- Independent Claims: Cover core inventions—likely the drug composition or therapeutic method.
- Dependent Claims: Specify particular embodiments, such as dosage forms, excipient combinations, or specific chemical derivatives.
Key Elements in the Claims
- Chemical Structure: If the patent claims a novel compound, the claims specify molecular structures, such as core scaffolds with defined substituents.
- Manufacturing Steps: Claims may delineate methods involving specific synthesis routes, purification steps, or formulation procedures.
- Usage Claims: Therapeutic methods tailored for particular indications, such as cancer, autoimmune diseases, or infectious illnesses.
Scope Evaluation
The claims are structured to cover a broad chemical or therapeutic space, potentially including:
- Broad claims: Encompassing all compounds or methods sharing core structural features or functional properties.
- Narrow claims: Limited to specific embodiments, such as a particular salt form, delivery system, or dosage.
The overall breadth depends on claim language precision—more general claims risk invalidation if prior art exists; more restrictive claims may limit licensing opportunities.
