The main factors that affect the success rate of trademark rejection reexamination depend on the "weight" and "quality" of the reexamination reasons stated in the reexamination application. In the case of knowing that worry-free is the applicant's successful rejection of the review, the following reasons are mainly put forward:

1. The trademark applied for is an unregistered trademark used by the applicant before. After long-term use and publicity, it has a certain popularity and reputation. The applied trademark has been widely used by the applicant, and has formed a one-to-one correspondence with the applicant, which has the proper distinction of trademarks.

2. The trademark applied for is a brand-new trademark with originality and distinctiveness designed by the applicant. Applying for approval of a registered trademark will not cause confusion and misunderstanding among the relevant public.

3. There are obvious differences between the applied trademark and the cited trademark in terms of constituent elements, drawing methods, overall appearance, prominent parts, calls and meanings, which will not confuse consumers and do not constitute an approximate trademark. Among them, the specific differences in components, painting methods, overall appearance, prominent parts, titles and meanings can be proved through detailed explanations to enhance persuasiveness.

4. According to the principle of consistency of examination standards, combined with this case, all the cited trademarks contain similar elements, which intersect in similar groups approved for use, but they are finally approved for registration. It can be seen that the fact that trademarks contain similar factors is not the decisive reason for rejection. Therefore, trademarks have their own distinctive features, which can distinguish the sources of goods or services, that is, they should be approved for registration.
