An earlier disclosure of the invention is non-prejudicial only if it occurred less than six months
before the filing of the European patent application and
was due to an evident abuse in relation to the applicant or to display at an exhibition falling within the terms of the Paris Convention on international exhibitions. Except in these two cases, the second of which is rare in practice, any disclosure of the invention before the date of filing or, if applicable, the earliest priority claimed (see point 4.1.021
) can be cited against the applicant as forming part of the state of the art, even if the applicant themself was responsible for the disclosure.
