How much does it cost to entrust an agency to apply for a patent?

How much it costs to entrust an agency to apply for a patent depends on what patent you apply for and what kind of service you choose according to your own needs. Anyway, as far as I know, the market for domestic agencies to apply for invention patents is probably that the basic service fee is around several thousand to ten thousand, and some famous agencies may charge more, starting from1w. In addition, the high-end intellectual property agent I entrusted at the time of application also told me that there would be additional official fees and service fees if the general patent claim exceeded 10.
