In this case, you hold a patent authorization certificate, but your patent does not have substantial protection rights
No one will sue you for infringement
But you can’t use your authorized patent for effective protection
If it’s just to apply for some government incentives, you can continue to pay fees and maintain the patent; if there is no use, for the sake of cost savings, you can no longer protect it. Just pay the annual fee to invalidate the patent
Theoretically, if you don’t take the initiative to defend your authorized patent, no one will declare your patent invalid, because the patent is declared invalid. You also need to pay an application fee
