A Patent Validity or Invalidity search requires extensive examination of the validity or invalidity of a patent or patent application in light of the prior art. The focus of our Invalidity or Validity search is to identify prior art references that may be used alone or in combination to challenge the validity of the claims in a patent or patent application.

• Patent validity search determines the strength of the patent under study and can, therefore, be useful for a client entering in licensing negotiations, as it can boost a patent’s commercial value in negotiations.
• An invalidity search is conducted to invalidate a competitor’s patent.

No stone will be left unturned to find the relevant prior art (“Always on Budget & Always on Time”)

The validity/invalidity search report includes the detailed analysis and mapping of potential prior art (patent and non-patent literature), against claims of the target patent or application in the form of claim charts. Important legal aspects such as antecedent and enablement issues, non-compliance to a duty of disclosure, etc. are also analyzed.
