Scope and Claims of JP2018516266
1. Nature of the Invention
Based on procedural and classification data, JP2018516266 generally addresses innovations in pharmaceutical compositions, specific chemical compounds, or drug delivery systems—common themes for patents of this nature. The core inventive concept often revolves around:
- A novel active pharmaceutical ingredient (API) or its derivatives
- A specific formulation or sustained-release system
- A method of manufacturing or treating particular conditions
2. Claim Construction & Focus
-
Independent Claims: These define the broadest scope, claiming a chemical compound, a composition, or a method involving the invention. The claims are typically structured as follows:
-
Chemical Compound Claims: Covering a specific chemical structure or a class of compounds with particular substituents or stereochemistry.
-
Use Claims: Claiming the use of the compound for treating a disease or condition.
-
Method Claims: Detailing processes for synthesis or administration.
-
Formulation Claims: Describing specific pharmaceutical compositions with stability, bioavailability, or release properties.
-
Claim Language Analysis: The patent's claims tend to be written with a mixture of Markush structures and functional language, securing broad protection within the inventive chemical or formulation space. This includes claims directed to:
- Specific molecular structures with key substituents
- Combinations with known excipients or carriers
- Methods of administration (e.g., oral, injectable)
3. Scope of the Patent
