Sommaire

Where a device which has been disclosed by public prior use contains a microchip on which a program written in machine language is stored which realises a control procedure, the said procedure does not form part of the state of the art under Article 54(2) EPC if no logic diagrams and block diagrams are available to skilled members of the interested public, if the principle underlying the control procedure is not discernible by inspection, and if, moreover, the technical possibility exists of ascertaining the contents of the program but experience suggests that, under the circumstances, especially in view of cost-benefit considerations, this cannot have occurred.
