A fee of 200 yuan for changing the bibliographic items shall be paid within one month from the date of request. Failure to pay within one month will be considered a withdrawal of the application! As can be seen from the above regulations, the fee for changing patent rights is generally two hundred yuan, and it will not take effect until the payment is completed within one month of application. Patent rights changes need to bring all the change materials to prove it, and apply to the patent agency. There is no need to worry about changes to patent rights abroad. As long as you follow the regulations, you can entrust others to handle it.
