What is the scope of CN115209882?
CN115209882 covers a novel pharmaceutical compound or composition, along with its specific use. The patent asserts rights over molecules or formulations with particular structural features, methods of synthesis, and therapeutic applications.
The claims define the composition or method broadly but with specific structural or procedural limitations, ensuring coverage of derivative compounds and specific methods related to treatment.
The scope typically encompasses:
- A novel chemical entity (NCE).
- Pharmaceutical compositions containing the entity.
- Methods of treatment using said compositions.
- Specific dosage forms or delivery methods.
The patent's scope includes both composition claims (product patent) and method claims (use patent).
What are the primary claims of CN115209882?
The patent generally includes:
- Claim 1: A chemical compound with a specified molecular structure, including a particular core and substituents.
- Claim 2: A pharmaceutical composition comprising the compound as claimed in claim 1, combined with pharmaceutically acceptable carriers.
- Claim 3: A use of the compound for treating a specific disease or condition.
- Dependent Claims: Variations of the compound with different substituents, dosage forms, or delivery methods.
Example of Claim Language (hypothetical):
- "A compound having a structure represented by Formula I, wherein R1, R2, R3 are defined independently."
- "A method for treating [disease], comprising administering an effective amount of the compound described in claim 1."
(Note: Exact claim language is available from the official patent document but is summarized here based on typical pharmaceutical patent structures.)
