Confirms whether a patent, design or trade mark at issue (whether it belongs to you or not) is valid with respect to the prior art. For patent validity this may cover both patent and non-patent literature. If relevant prior documentation is found that was not located by the examiner, the patent can be opposed or revoked on the basis that it was incorrectly granted.

Validity searches are therefore useful if a competitor is considering infringement proceedings. Alternatively, if you want to take legal action for infringement of your own patent, or are approaching a company to arrange a licensing deal, a validity search may be required to decide if the patent in question is vulnerable to legal challenge.

We can also pursue verification of the date of public availability of documents located by ourselves or other parties should this be required for court proceedings.
