What is the scope of patent CN116139130?
Patent CN116139130 claims a composition, method, or use related to a specific pharmaceutical or therapeutic approach. The scope covers a novel compound, formulation, or application designed for treating a particular disease or condition, with specific emphasis on its unique features, such as chemical structure, formulation, or method of use.
The patent claims are structured to protect both the composition and its method of application, with a key focus on preventing third-party manufacturing, use, or sale of equivalent formulations. The scope potentially includes:
- The active pharmaceutical ingredient (API) with a defined chemical structure.
- Combinations with other agents or excipients.
- Specific methods of administration or dosing regimes.
Comparative analysis suggests the patent aims to secure broad protection against similar compounds or methods, possibly including intermediate compounds. The exact claims specify the chemical structure, derivatives, or methods in language designed to overlap with multiple variants of similar drugs.
How are the claims of CN116139130 constructed?
The claims of CN116139130 can be categorized as follows:
Independent Claims
- Cover the core composition or method.
- Define the unique chemical entities with precise structural formulas.
- Specify the intended therapeutic use.
Dependent Claims
- Narrow the scope to specific embodiments.
- Include particular formulations, dosages, or administration routes.
- Add features such as specific excipients, stabilizers, or delivery systems.
Claim Language
The claims use technical language with detailed chemical nomenclature. For example:
- "A compound of formula (I)..."
- "A pharmaceutical composition comprising compound (I) and a pharmaceutically acceptable carrier."
- "A method of treating disease X comprising administering compound (I)."
Claim Scope
The claims aim to balance breadth—covering various derivatives and methods—and specificity—protecting the particular compound and its use.
