This decision by the FCJ confirms that, when assessing the disclosure of a prior art document, it is not permissible to supplement the disclosure with specialist knowledge of a person skilled in the art.

The FCJ also confirmed that prior art documents filed during appeal proceedings are to be admitted into the procedure if the Patent Court in its hint issued in accordance with sec. 83 para. 1 German Patent Act indicated that the Plaintiff’s reasoning on a particular point was deemed to be correct.
