Invalidity Search
Locate prior art that could invalidate a patent asserted against you — or test your own.
The question it answers
“Is there prior art, dated before the priority date, that anticipates or renders obvious the claims of this patent?”
An exhaustive search for prior art dated before the target patent's priority date, focused on the independent claims that matter. Used in litigation, opposition, licensing negotiations and to stress-test your own portfolio before enforcement.
Who it's for
- Companies facing an infringement assertion
- Litigation and opposition counsel
- Patent owners validating assets before licensing
