You can know the category of diamond trademark at the first time through inquiry. After all, there are really many choices in Bajie Intellectual Property Trademark Classification Encyclopedia, but the most suitable choice will never change much there. Therefore, it can be recognized that the category of diamond trademark is "1403- jewelry, jewelry, precious stones and precious metal souvenirs-diamond 140035".
Regarding trademark registration, under normal circumstances, enterprises often choose two registration methods. One is to go directly to the Trademark Office for trademark registration, and the other is to entrust an agency for trademark registration. The time to use these two methods will not change much, usually about one year, provided that everyone understands the rules and does not refuse to disagree.
For some work in the registration process, there will definitely be a large number of display queries, and the trademark query is rejected so that similar trademarks will not be encountered immediately in the later review. Although the trademarks that enterprises can find when inquiring don't include blind trademarks, those trademarks can't be found during this period anyway, so even if they are inquired, there is a risk that the trademarks will be rejected.
However, the probability that a trademark that has not been inquired will only be rejected is greater, so even in order to increase the probability of passing, it is necessary to inquire before trademark registration. Moreover, trademark inquiry can also prepare multiple related trademarks for many times, which can make complete preparations for the blind period.
Of course, the trademark cannot be registered immediately after the inquiry, so you should know whether the preparation materials for this trademark are complete. Personal trademark registration and enterprise trademark registration should also be distinguished. Although the nature is similar, the materials prepared will still be somewhat different and cannot be generalized.
In fact, trademark registration is not everyone's concern. When the trademark registration is approved and the Trademark Registration Certificate issued by the Trademark Office is obtained, the enterprise will have the trademark, and the use and subsequent development of the trademark will be decided by the enterprise itself. However, it should be remembered that it will be helpful to use the trademark as soon as possible and keep the evidence of use.
