Generally, there are service fees through agents, some in 200 yuan, and some may be more.
The certificate fee for invention patent is 255 (stamp duty is calculated in 5 yuan), and the certificate fee for utility model and design is 225 (stamp duty is calculated in 5 yuan).
In addition, you need to pay the annual fee of the year of authorization, ranging from 600- 1200, depending on the type of patent you apply for and the time of authorization. Judging from the amount, your fee has been slowed down, otherwise even the utility model authorized in the first year will have to pay more than 800 yuan.
Besides, do you have to pay maintenance fees? This fee only needs to be paid three years after applying for authorization, because I don't know my specific situation and can't judge. The maintenance fee is 300 yuan/year, and the certificate fee is also paid.
So you'd better consult the patent office directly at 0 10-62085588, and the service staff in the information center will tell you how to handle it.
If you want to cancel the agency relationship, you need to go through the formalities of canceling the entrustment. Submit the filing application for project change and the supporting materials signed by you to 50 yuan, and the entrustment relationship can be terminated in about one month.
