How to Renew a Patent in China?
While a Chinese patent is in the pending application stage, no maintenance fees are due. Once a Chinese patent is granted, you are obliged to pay a recurring renewal fee to maintain the patent. The first annuity after grant of a patent is paid within two months from the date of receipt of the Notice of Allowance from the Chinese Patent Office (CNIPA). The renewal due date for all subsequent renewals will fall on the anniversary of the filing date.
For example, if the filing date of a patent is 18.12.2006 and the grant date of the patent is 26.06.2012. You will only have to settle the first renewal fee starting from 27.06. 2012 till 26.08. 2012. The next annuity will be due renewal on 18.12.2013 (from the anniversary of filing date).
