Failure to pay the patent fee will result in the invalidation of the patent.

You can continue to pay the annual patent fee within six months (including exactly six months) after the deadline. After six months, the patent right will be terminated.

Anyone who has had a patent knows that a patent needs to pay an annual fee. The amount of annual fee is or increases with the increase of guarantee time, that is to say, it will be paid more every year than the previous year.

Because I need to pay the annual patent fee every year, I forget the time to pay the annual patent fee. Can I recover if I forget to pay the annual patent fee?

There is a time limit for patent payment. Within six months (including exactly six months) beyond the time limit, the repayment can be continued. Details are as follows:

(1) If the term exceeds 1 day to 1 month (including 1 whole month), only the annual fee needs to be paid, and there is no need to pay the late fee;

(2) If it exceeds 1 month to 2 months (including 2 whole months), the amount of overdue fine payable shall be 5% of the annual fee;

(3) If the overdue payment is more than 2 months to 3 months (including 3 whole months), the amount of overdue payment shall be10% of the annual fee;

(4) If the overdue payment is more than 3 months to 4 months (including 4 whole months), the amount of overdue payment shall be 65438+ 05% of the annual fee;

(5) If the overdue period is more than 4 months to 5 months (including 5 whole months), the amount of overdue payment shall be 20% of the annual expenses;

(6) If the overdue period is more than 5 months to 6 months (including 6 whole months), the amount of overdue payment shall be 25% of the annual expenses.

But after more than six months, the patent right was terminated.
