(1) Several designs may be combined in one application (multiple application). The multiple application may not comprise more than 100 designs.
(2) The applicant may divide a multiple application by declaration to the German Patent and Trade Mark Office. The division does not affect the date of filing of the application. If the sum total of the fees which would have to be paid for each divisional application in accordance with the Patent Costs Act (Patentkostengesetz) is higher than the application fees which have been paid, then the differential amount is to be subsequently paid.
