2.2 Key Claim Elements
| Claim Element |
Description |
Scope |
| Active Ingredient X |
The invention centers on compound X, with defined purity levels |
Protects the specific chemical or biological entity |
| Carrier or excipients |
Specific carriers or excipients used with ingredient X |
Ensures formulation patentability |
| Method of administration |
Specific dosing or delivery routes |

2.3 Sample Claim Example (Simplified)
"A pharmaceutical composition comprising active ingredient X at a concentration of Y%, in combination with excipients A and B, for use in treating disease Z."
This represents a typical composition claim — precise concentrations, combinations, and intended use.
2.4 Claim Scope and Limitations
- Broad Claims: Often limited by prior art; challengeable if similar formulations exist.
- Narrow Claims: Offer higher validity but restrict scope.
Key risk: Overly broad claims may be invalidated for lack of novelty, whereas narrow claims risk circumvention by minor modifications.
