First of all, we must understand that if we don't pay the annual fee on time, it will have a very serious impact on us. If it is overdue within one month, and the patentee fails to pay the annual fee within the prescribed time limit, or fails to pay the annual fee in time within the extended period, the patent may be directly extended without paying the late fee. Of course, if the annual patent fee is overdue for 2~6 months, you must pay enough fees after receiving the relevant notice from the patent management department, including annual fee, late payment fee and so on.
And pay 5%, 10%, 15% and 20% of the annual fee respectively. Those who fail to pay the annual fee for more than six months will receive a notice of patent termination from the administrative department. However, in this case, the patentee can still retain the relevant patent right and pay the corresponding annual fee on time within two months from the date of receiving the notice.
Therefore, we can clearly know that patents have a great influence on us, and we must pay the corresponding patent fees on time, and don't break the contract or delay, because the consequences are very serious for us and beyond our capacity.
