Impact on Scope |
| Independent Claim 1 |
A pharmaceutical composition comprising a novel active ingredient X in a specified dosage form |
Core protection of the main invention |
| Dependent Claim 2 |
The composition of claim 1, wherein the active ingredient X is present in a concentration of Y |
Adds specificity, limits the claim scope |
| Independent Claim 3 |
A method for treating disease Z involving administering the composition of claim 1 |
