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 deemed as a withdrawal of the application! As can be seen from the above regulations, the patent right change fee is generally charged two hundred yuan, and it will not take effect until the payment is completed within one month of application. Patent rights changes need to be accompanied by all the change materials and submitted 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.
