As a prerequisite, copies of the material to be presented must be provided in good time before the oral proceedings, i.e. Rule 116 applies. These copies are treated like any other submission made in writing.
The Opposition Division should decide whether the presentation of a computer-generated slideshow would facilitate the proceedings, after having heard the parties and taking into account whether allowing or refusing the use of the presentation would be detrimental to any participant.

If copies of the material to be presented have not been filed in good time, or if the slides contain new matter, the presentation may be disregarded under Art. 114(2) and Rule 116. In this case the Opposition Division will apply the same criteria for admissibility as are used for other late-filed facts or evidence (see E-II, 8.6).
