Homophonic advertising idioms are also the crystallization of businessmen's wisdom, and a more effective way to protect advertising terms is through trademarks. This case once again clarified that homophonic idioms or words with positive significance can be used and registered as trademarks. This kind of trademark may be rejected because of the subjective differences of examiners in the examination stage of the Trademark Office, but there is still a great chance to win the exclusive right to use the trademark through reexamination. Therefore, when this kind of trademark is rejected, it is suggested to conduct a positive review in order to fight for rights.
