Main Claims Breakdown
Patent US11,951,096 contains a series of claims, particularly:
| Claim Type |
Description |
Scope & Protective Edge |
| Independent Claims |
Cover core compounds/formulations and their uses |
Broader protection covering the main inventive molecule and its primary uses |
| Dependent Claims |
Specify particular variants, modifications, delivery methods, etc. |
Narrowing scope, providing fallback positions and detailed coverage of embodiments |
| Method Claims |

Protection for proprietary synthesis pathways and therapeutic protocols |
Core Chemical or Composition Claims
The main independent claim (example):
"A pharmaceutical composition comprising a compound of Formula I, or a pharmaceutically acceptable salt, hydrate, or solvate thereof, for use in treating [specific disease]."
This indicates protection over:
- Chemical structure (Formula I) with potential substitutions
- Salt/hydrate/solvate forms enhancing stability or bioavailability
- Therapeutic application—targeted indication (e.g., cancer, neurological disorder)
Claim Scope Analysis
- Chemical Scope: The claim includes derivatives maintaining the core structural motif, facilitating broad coverage.
- Functional Scope: The use in treating specified conditions opens avenues for patent infringement in various formulations and administration methods.
- Method of Use: Claims on specific treatment methods strengthen enforceability in clinical or off-label scenarios.
Limitations and Scope Boundaries
- The scope depends on the scope of Formula I and its derivatives.
- Narrower claims on specific salts or delivery systems serve as fallback positions.
- Additional claims may limit scope to specific dosages, combinations, or methods.
