The first is to modify the plan and re-apply, and the second is to do a rejection review.
If a trademark is rejected because of lack of distinctiveness, it is difficult to reject the review, but if it is rejected because it is similar to another trademark, then the review can be rejected.
However, for non-professionals, it is not easy to distinguish whether a trademark lacks distinctiveness or is similar to other trademarks. Therefore, when applying for trademark registration, it is recommended to entrust an agent registered with the Trademark Office. The organization conducts it. This can help avoid the risk of errors and increase the success rate.
