Compared to a single-class application, a multi-class application reduces the overall filing time since only one application and one copy of relevant attachments are required – the application procedures are thus simplified. Moreover, costs are also reduced because after the multi-class application is approved for registration, government fees related to the recordation of change, assignment, license or pledge will be calculated "per application". It should, however, be noted that:
filing fees, registration fees and renewal fees are calculated "per class" rather than "per application";
in dividing a trademark, the division fees for the increased trademarks and the fees for disputes resolution, if applicable, shall also be paid; and
in the case of a multi-class application, the issue of multiple priorities may arise.
