If, on reaching the search division, an application has been found to be incorrectly preclassified and thus inappropriately distributed, it is redistributed by the search division receiving it, indicating the appropriate amendments on the dossier and in the EPO's in-house electronic tool. Normally this is done by mutual agreement with the search division to which it is proposed to redistribute it. However, cases arise over which there is disagreement or uncertainty regarding classification boundaries, or where the search division dealing with the case is uncertain as to its correct preclassification. In such instances the search division having the case does not spend time in trying to resolve the matter, but forwards the file to one of a team of appointed specialists in classification matters.
