CTM owners who have opted to be notified will have the option to renew their opt-in for a further three-year period, but no notices will be issued to remind them that expiry of the initial opt-in is imminent.  

It rather looks as though the notification service -- apparently the only such service offered to CTM owners by any national office within the EU -- would have been terminated but for the fact that the cost of fiddling around with the IPO's software would be too great within the confines of current public spending cuts.
