How to calculate the patent late fee?

In fact, the algorithm of patent late payment fee in China is more humanized. As long as the patentee does not exceed the specified period of 1 day to 1 month (including 1 whole month), the patentee only needs to pay the annual fee without paying the late fee; This period of time can be described as a buffer period for patent late fees. It is very good to give the patentee a month's time buffer, so that the patentee can pay the annual fee on time unless he is too busy to apply for a patent.

If the patentee exceeds the prescribed time limit 1 month to 2 months (including 2 whole months), then the patent late payment fee needs to be paid at this time, and the amount of late payment fee to be paid is 5% of the full annual fee; By analogy, if it is more than 2 months to 3 months (including 3 whole months), the amount of overdue fine to be paid is10% of the full annual fee; For 3 months to 4 months (including 4 whole months), the amount of overdue fine to be paid is 65438+ 05% of the annual expenses, etc.

In a patent application, the patentee generally does not forget to pay the annual fee. If the patentee forgets to pay the ordinary patent office, there will be relevant reminders. Of course, there may also be cases where the patentee forgets to pay the patent application fee. Remember to pay the late fee at this time. If the patent late fee is not paid for more than six months, the Patent Office will regard the patentee as giving up the patent and make it public directly.
