The trademark publication is the declaration for the third party's appeal in the official brand newsletter after the application of the trademark. The publication period in the official brand newsletter is three months. This three month period may be appealed to the declared brand in the official brand newsletter
Similar brands that may interfere with the trademark from time to time may be declared in the official brand newsletter. The third person is entitled to appeal to the brand publication within the time period.
If there is a trademark that is likely to be confused with the same or similar goods or services that have already been filed or registered, the trademark may appeal to the declared brand in the official brand newsletter. In other words, if the trademark application that was published was made with bad intentions; an appeal to trademark publication could be made.
In addition, even if the trademark you have used is not registered; if you have information and documents to prove that you have obtained through the use of brand-based trademark right you may appeal for using the right to use the brand.
