The previous patent application link needs to pay patent fees according to the type of patent application. Generally speaking, the cost of substantive examination of expensive invention patents is 2500 yuan, and it is basically cheaper for utility model patents and design patents to fail substantive examination. The way to apply for payment can be through personal application or through agency. The application process mainly needs to pay for other materials. The latter is the annual fee that needs to be paid after the application is successful. If it fails to pay within the specified time or the amount paid is insufficient, it can be repaid within 6 months from the date of expiration of the annual fee, and the corresponding amount of late payment fee will be paid, otherwise the patent right will be lost! The late payment fee is: if it exceeds 1 day to 1 month (including 1 whole month), only the annual fee is required, and no late payment fee is required; If the overdue payment exceeds 1 month to 2 months (including 2 whole months), the amount of overdue payment shall be 5% of the full annual fee; 2 months to 3 months, 10% annual fee; 3 months to 4 months, 15% annual fee; 4 months to 5 months, 20% of the full annual fee; 5 months to 6 months, which is 25% of the full annual cost.
It is suggested that you pay the patent fee on time to avoid unnecessary things that lead to your patent application failure or patent publication, which is not worth the candle; In fact, preferential policies for patent application are constantly being introduced, such as the national patent fee reduction policy and the proportion of patent application fee reduction, which are beneficial to the patentee. Greatly reduced the economic pressure of the patentee.
