Do you want to challenge a questionable third-party patent? We can search for publications which could challenge the novelty or inventive step of the patented invention in question.
You can find the most important information on how we proceed with such a search as well as what is possible technically summarised in the Validity Search product flyer.
On request, we analyse in-depth the novelty and inventive step of an invention with regard to the state of the art as defined by you. Such in-depth analyses of validity can either be conducted independently or as a follow-up to a search. You can use the results as the basis of argumentation in patent disputes before a court, for example. It does not however constitute official information nor obligate the IPI in any possible official procedures.
The Validity Search is also known as Opposition Search, Invalidity Search, Patentability Search, Novelty Search or Prior-Art Search.
