1. The same or similar trademarks were not found when the application was submitted because there was a blind period of trademark inquiry for several months, during which the Trademark Office did not enter the information into the microcomputer system, so some trademarks could not be found.

2. In your second case, if your registered English trademark is used together with another person's registered Chinese trademark, your whole trademark has no legal effect, and if you use another person's Chinese trademark in the same category, others can sue you for infringement, so it is suggested that the landlord use another Chinese name and apply for registration, which can better protect your rights and interests.
