When a material error is found to be present in a search report prior to publication thereof, a new search report will be drawn up which supersedes the preceding one. Where the search report has already been sent to the applicant according to Rule 65, but has not yet been published, the error should immediately be notified to the applicant. When a serious error is noted following publication of the search report, a corrigendum is published in the European Patent Bulletin, and the applicant and the Examining Division should be informed accordingly. If the error comprises the transmission of an incorrect document as a citation, the correct document should be sent.
