What is the Scope of Patent CN114727948?
Patent CN114727948 pertains to a pharmaceutical invention, focusing on a specific formulation, compound, or method. Its scope defines the boundaries of the protected technology and outlines what others cannot commercially exploit without authorization.
The patent claims protection over a novel chemical compound or a combination of compounds, along with methods of synthesis or application. The patent emphasizes novelty, inventive step, and industrial applicability. The scope includes:
- The chemical structure or formula, if disclosed.
- The preparation method, if claimed.
- The specific therapeutic application or method of use.
- Possible formulations, dosage forms, or delivery systems.
The patent documents specify the core claims explicitly derived from the detailed description, which delineates the boundaries for infringement and licensing.
What Are the Key Claims of CN114727948?
The patent's claims are structured into independent and dependent claims.
Independent Claims
- Cover the novel compound or composition with specific structural features.
- Encompass methods of manufacturing the compound.
- Include therapeutic application claims, such as treatment of a particular disease.
Dependent Claims
- Narrow the scope by incorporating specific embodiments.
- Define particular substituents, concentrations, or formulations.
- Specify methods of administration, dosing regimens, or combination therapies.
Example of Typical Claims
While the exact language is proprietary, typical claims in this class cover:
- A chemical compound with a detailed structure listed in the claims.
- A method for synthesizing the compound with defined steps.
- Use of the compound for treating tumor-related diseases, autoimmune diseases, or other specific indications.
The claims emphasize inventive features over prior art, including unique substituents or synthesis pathways that improve efficacy, stability, or reduce side effects.
