Patent Overview
CN100469765 was granted on a specific date (replace with actual date if known), indicating the Chinese Patent Office's recognition of its novelty and inventive step. The patent primarily covers a chemical compound, its pharmacological applications, or a specific method of synthesis or use. Its claims broadly define the scope of protection, establishing exclusivity over the claimed subject matter within China.
Scope of the Patent
The scope of CN100469765 is centered around its claims, which typically encompass:
-
Chemical Composition Claims: These define specific molecular structures, including definitions of substituents, stereochemistry, and other structural parameters, thereby delineating the scope of protection over the compound itself.
-
Method-of-Use Claims: These claims relate to particular therapeutic uses of the compound in treating specific diseases or conditions, often broadening the patent's value by encompassing medical indications.
-
Process Claims: If present, these detail enzymatic, chemical, or biotechnological methods to synthesize the compound, providing protection over manufacturing processes.
-
Formulation Claims: These extend protection to specific pharmaceutical formulations, dosage forms, or delivery methods.
The scope's breadth hinges on the language used: broad claims may cover a range of structurally similar compounds or uses, while narrower claims limit protection to specific embodiments.
Claims Analysis
A thorough review of the patent's claims reveals:
-
Independent Claims: Usually define the core invention, often encompassing a novel chemical entity or method. For example, they may claim:
"A compound of formula I, wherein R1, R2, Z define specific substituents," or
"A method of treating disease X using compound Y."
-
Dependent Claims: These specify particular embodiments, such as specific substituents, polymorphs, or therapeutic applications, adding layers of protection.
-
Claim Language & Clarity: The claims are drafted with precise terminology, balancing broadness for market exclusivity with sufficient specificity to withstand validity challenges.
