As you will see the Examiner regards the LAPORTE reference as being of particular relevance and has drawn attention particularly to page 2 lines 3 to 14 and 21 to 62. The reference to the cerium oxide is however, only one in a list of a large number of possible oxides and there is no specific disclosure of cerium in the weight range specified in the present claims. The next stage will be publication of the search report and this will trigger the start of the 6 months period for filling the request for examination. I will write to you again as soon as I have the notice of intended publication of the search report. Yours sincerely DC TUNBRIDGE WELLS: I BOYNE PARK, TUNBRIDGE WELLS, KENT, TN4 8EL. TEL.
