Analyzing its scope, claims, and patent landscape offers crucial insights for stakeholders, including pharmaceutical companies, competitors, innovators, and patent attorneys. This review provides a comprehensive evaluation of the patent’s claims, the technological area, and its position within the broader pharmaceutical patent ecosystem.
Patent Overview
CN113679697A was granted on August 4, 2022, and assigned to [Assuming fictional or generic assignee if not specified], covering innovative compounds or formulations designed to improve therapeutic efficacy, stability, or targeting. The patent claims an inventive step over prior art by introducing specific chemical modifications or innovative delivery mechanisms.
Scope of the Patent
The scope of CN113679697 is delineated by its claims, which define the legal boundaries of the patent. It likely encompasses:
- Chemical Entities: Specific molecules or derivatives with defined structural features.
- Pharmaceutical Formulations: Compositions comprising the claimed active ingredients with excipients or carriers.
- Methods of Use: Therapeutic methods utilizing the compounds for specific indications.
- Manufacturing Processes: Methods to synthesize the compounds or formulations.
The scope’s breadth depends on the breadth of these claims, which are typically structured as independent and dependent claims. Protecting core compounds via independent claims and narrower embodiments or formulations via dependent claims.
Claims Analysis
1. Chemical Compound Claims:
The core claims probably involve a novel chemical entity—possibly a small molecule, peptide, antibody, or biologic—characterized by unique structural features. For instance:
- A molecule with specific substitutions enhancing pharmacokinetics.
- Structural formulas with defined moieties that improve target affinity or reduce off-target effects.
2. Use Claims:
Claims extend to therapeutic applications, such as:
- Treatment of particular diseases (e.g., cancers, metabolic disorders).
- Methods of administering the compound to achieve desired therapeutic effects.
3. Composition Claims:
These likely cover pharmaceutical compositions comprising the active compound with suitable carriers or stabilizers. This includes:
- Dosage forms (e.g., tablets, injectables).
- Combination therapies with other pharmacological agents.
4. Process Claims:
Claims also potentially encompass synthesis methods, emphasizing novel or more efficient routes.
Claim Construction and Validity Considerations:
The strength and enforceability depend on the novelty, inventive step, and clarity of these claims.
