In oral proceedings a computer-generated slideshow cannot be used as a matter of right, but only with the permission of and at the discretion of the Examining or Opposition Division (T 1556/06).
Care should be taken that presentations of computer-generated slideshows do not negatively impact the efficient conduct of oral proceedings (e.g. interruptions for the technical preparations for the presentation).Similar considerations apply to the use of other visual aids (e.g. flipcharts, pictures).
Furthermore, with computer-generated slideshows it must be borne in mind that since the EPO does not provide any equipment such as computers or projectors, requests to provide equipment for the presentation of a computer-generated slideshow must be refused. Screens, however, should be available in most meeting rooms.
