If the competent department decides of its own motion to obtain an expert report (D-VI, 1, 6th paragraph), it will have to decide in what form it should be submitted by the expert whom it appoints. The report should be drawn up in written form only in cases where the competent department considers that this form is adequate in view of the content of the report and provided that the parties agree to this arrangement. As a rule, in addition to submitting a written report and introducing it orally, the expert will also be heard (see IV, 1.6).

A copy of the report must be submitted to the parties. The copy will be produced by the EPO.
