If you originally applied by an agency, you don't need to change your address because all relevant documents are sent to your agency.
If you apply by yourself and leave your contact information, I suggest you make some changes.
You can download "1000 16 Statement of Project Change" from China National Intellectual Property Administration website.
Then fill it out as required.
According to your situation, just fill in the column 1, followed by the applicant and contact person.
Then attach a copy of your changed business license address and affix your official seal or something.
Send it to China National Intellectual Property Administration with the document.
Because I don't specialize in this job, I still know that the charge is not that expensive. In fact, China National Intellectual Property Administration has clearly stipulated the charging standard. If the information of the applicant (patentee) is changed, a change fee of 200 yuan shall be paid for each patent.
For a patent application (or patent), if the applicant makes continuous changes to the same bibliographic item in the procedure of reporting changes to the bibliographic item, it shall be regarded as a change. Where the applicant requests to change the inventor and/or the applicant (or the patentee), it shall pay the 200 yuan for the change of specification items and the 50 yuan for the change of patent agency and/or patent agent.
For example, if the applicant requests to change the applicant of a patent application from A to B, and then from B to C, it is deemed that the applicant has changed, and the description of the change must be paid to 200 yuan. If the inventor's name is changed at the same time, the applicant only needs to pay the filing project change fee once, 200 yuan.
Another example is that when the applicant requests to change the applicant of a patent application from A to B and change the patent agency and agent at the same time, the applicant shall pay the filing project change fee 200 yuan and the agency and agent change fee 50 yuan.
