Definition
A dependent claim is a patent claim that refers back to and adds limitations to an independent or earlier claim, narrowing its scope.
Why It Matters Legally
Dependent claims provide fallback protection if a broad independent claim is invalidated. They add layers of defense and can capture specific commercial embodiments.
Example Use Case
If the broad independent claim is invalidated, a narrower dependent claim adding a specific material may still survive and be infringed.
