In addition, you need to pay an annual fee to safeguard the patent right. If the annual fee is not paid on time, the worst thing may be to terminate the patent right as an automatic waiver.
Therefore, to sum up, we can understand the patent expiration as two situations:
1, when the patent expires, the protection shall be terminated according to law;
2. Failing to pay the annual fee and overdue fine after the annual fee payment period;
It is worth noting that, according to the relevant regulations, if the applicant fails to pay the annual fee and late payment fee in full, the patent right will be terminated from the date of expiration of the previous year.
The above is about what to do when the patent application period expires. Most patent applicants will feel that as long as it is a good project, they can complete the application without copying or imitating other people's projects. You should know that the whole process of patent application is quite long and difficult. If you want to improve the success rate of patent application, you must find a reliable patent agent. Because there are too many patent agencies to choose from in the market now, many people will choose because of the low price. Never cooperate with an agent just because the price is low. It is very likely that there will be some problems when they cooperate.
