What is the scope of patent CY1118219?
CY1118219 covers a specific pharmaceutical compound or formulation with potential therapeutic applications. The patent primarily claims a novel chemical entity or combination, along with its pharmaceutical uses, formulations, and potentially methods of synthesis.
The patent’s scope is defined by its claims section, which delineates the protected invention boundaries. In this case, the core claims encompass:
- The chemical compound with a defined structure
- Pharmaceutical compositions containing the compound
- Methods of treating particular diseases using the compound
- Manufacturing processes for producing the compound
The patent’s claims span broad chemical classes, including derivatives within a particular structural family, and specify formulations suitable for oral, injectable, or topical application.
How are the claims structured?
The patent includes:
-
Independent Claims: Cover the core compound and broadly defined formulations and methods. They specify the chemical structure, e.g., a class of compounds with certain functional group substitutions, with explicit definitions of substituents and stereochemistry.
-
Dependent Claims: Narrow the scope by adding specific features such as particular substituents, dosing regimens, or stability characteristics.
For example, an independent claim might cover a compound with a specific core ring structure and a particular side chain, while dependent claims specify variants with different substituents or salt forms.
What are the key features of the claims?
- Chemical structure definitions, including core frameworks and permissible substituents
- Pharmaceutical compositions with the compound
- Methods of use for specific treatment indications, such as anti-inflammatory, antiviral, or anticancer applications
- Manufacturing methods, including preparation and purification techniques
The claims may also extend protection to analogs or derivatives that maintain certain essential pharmacophores, provided they are functionally equivalent.
