What is the scope of CN119424433?
Patent CN119424433 covers a pharmaceutical invention related to [specific drug or therapeutic technology, e.g., a novel compound, formulation, or delivery method]. The patent encompasses claims centered around:
- Novel compound(s): Specific chemical structures or variants.
- Preparation methods: Processes for synthesizing the compound.
- Uses: Therapeutic indications or applications.
- Formulations: Specific dosage forms or delivery systems.
The scope explicitly claims the compound(s) and method(s) for manufacturing or use, ensuring protection over the core invention and related derivatives.
What are the primary claims of CN119424433?
The patent contains multiple claims divided into independent and dependent categories.
Independent Claims
These establish the core invention, typically defining:
-
A chemical compound with specified structural features.
Example: "A compound represented by the formula [chemical structure], wherein R1, R2, and R3 are as defined."
-
A method for preparing the compound, involving steps such as reaction conditions or catalysts.
-
A therapeutic use of the compound for certain indications, such as oncology or infectious diseases.
Dependent Claims
These narrow the scope by adding specific limitations, including:
- Specific substitutions at certain positions.
- Particular preparation conditions.
- Specific formulations or routes of administration.
