Example of an independent claim:
“A compound selected from the group consisting of [specific chemical structure], or a pharmaceutically acceptable salt, ester, or prodrug thereof, for use in the treatment of [indication].”
Implication: This claim covers a class of compounds rather than a single molecule, possibly offering broad coverage if valid.
Claim Novelty and Inventive Step
- Novelty: Based on prior art searches, the claimed compounds or methods are distinguished by unique structural features or unexpected therapeutic benefits.
- Inventiveness: The claims likely involve inventive step if they demonstrate non-obvious advantages over prior art, such as improved efficacy, reduced side effects, or ease of formulation.
