CLR III G 4.2.4 Other written evidence

In T 332/87 a dated internal paper, marked as being confidential and not signed, was – together with an undated leaflet – not considered sufficient evidence. In T 595/89 the board decided that the opponent's in-house documents relating to the installation of a device in an aeroplane and to the sale thereof were not sufficient to prove public prior use.

CLR III G 4.2.1.C Events long past

In T 1191/97 the appellant's criticism of the evaluation of evidence by the department of first instance did not pose a serious threat to the witness's credibility. The fact that the events at issue had taken place a long time ago could readily explain certain imprecisions in the witness's testimony. The board saw no indication that the witness had been in breach of his obligation to testify to the best of his recollection.
