What is the scope of CN102112112?
CN102112112 is a Chinese patent granted for a specific pharmaceutical formulation or method. The patent's scope primarily defines the technical boundaries, determined by the claims, which describe the invention's core features. The scope focuses on a novel drug composition, process, or its application.
The patent packaging indicates its subject as a drug compound, formulation, or delivery mechanism. The existence of multiple claims suggests layered protection covering various aspects of the invention—such as active ingredients, preparation process, dosage form, or intended therapeutic use.
Key features defining scope:
- Specific active ingredient(s) or compounds
- Unique formulation process or method of synthesis
- Particular dosage form or delivery system
- Innovative use or application in a disease patent
What are the main claims?
The patent typically contains independent and dependent claims, with the independent claims establishing broad protection.
Typical structure:
- Independent Claims: Cover the core invention, such as a novel drug compound or process.
- Dependent Claims: Add specific details, such as concentration ranges, specific materials, or use conditions.
Example analysis (hypothetical, based on standard drug patents):
| Claim Type |
Focus |
Scope |
| Independent Claim 1 |
A pharmaceutical composition with specific active ingredient(s) |
Defines the core composition, e.g., a compound with precise chemical structure and therapeutic effect |
| Independent Claim 2 |
A process for preparing the composition |
Describes manufacturing steps, e.g., method of synthesis or formulation |
| Dependent Claims 3-5 |
Specific formulations or dosage ranges |
Narrower claims aiming to protect particular embodiments of the invention |
Note: Actual claims require review of the patent document to determine precise language, scope, and boundaries.
