Do I have to pay for patent application? How much does it cost to come down altogether? How long will it take to approve?

Hello, you need to pay for patent application. If you apply by yourself, you only need to pay the official fee. The official fee depends on what patent you apply for, which is divided into: invention patent, utility model patent and design patent. These three official charges are different! If you are looking for an intermediary, you have to pay a certain agency fee to the intermediary in addition to the official fee, but it saves a lot of trouble. For example, if you apply yourself, you don't have to write the materials. Actually, writing application materials is quite troublesome. Maybe, you won't apply! My suggestion is that it is more reliable to find an intermediary, of course, the intermediary should also find a higher qualification! Like us! Hehe, the general application is unsuccessful, and no agency fee is charged! thank you
