Getting the acceptance notice means that your trademark has passed the formal examination and entered the substantive examination, and the whole substantive examination will take about 9 months to complete. Because there are many factors affecting trademark registration, it is very necessary to search before trademark application in order to improve the success rate of trademark registration. It should be noted that although trademarks marked TM can be used, they are not protected by law. Only when you really get the trademark registration certificate, the trademark is yours, and the validity period of the trademark is 10 year.
