2.2 Claim Breadth and Validity Analysis
| Aspect |
Analysis |
Comments |
| Novelty |
Claims distinguish from prior art based on [e.g., specific structural motifs, delivery modes] |
Validation requires thorough prior art search |
| Inventive Step |
Features such as [e.g., unique linker groups, targeting moieties] provide inventive activity |
Existing compounds with similar structures challenge non-obviousness |
| Clarity |
