1, you said that some changes have been made to the LOGO "from eight letters and four Chinese characters to six letters and four Chinese characters", but legally speaking, the trademark you changed already belongs to another trademark, and you need to apply for trademark registration again, so that you can enjoy the exclusive right of the changed trademark without going through any change procedures.

2. Application for trademark registration:

You can go to the State Trademark Office yourself; You can also entrust an agency to handle it for you.

The official fee for trademark application is 1000 yuan, and the agency fee generally ranges from 600-800 yuan.

The period of trademark registration is about one year to one and a half years. Because the State Trademark Office examines trademarks by category, this time is not fixed, depending on the category of your registered trademark. If it is fast, it will come down in less than a year, if it is slow, it will come down in two years.

Hope to adopt, thank you.
