How much is the patent invalidation fee? How to deal with invalid patents? Applying for a patent is not smooth sailing, so it's best to put it on record and plan ahead. There are only two results in applying for a patent, one is that the application is successful, and the other is that the application fails; There may be cases where the application process is smooth but the objection in the middle is invalid. Of course, if your patent is infringed by others, you can achieve it by invalidating the patent. What is the specific patent invalidation fee? How much is the patent invalidation fee? Let's first understand the concept of patent invalidation. The so-called patent invalidation refers to the act that after the patent right is granted, it is found that it does not meet the conditions for granting the patent right in the Patent Law and its implementing rules, and it is declared invalid after reexamination and confirmation by the Patent Reexamination Board. The declared patent right was considered nonexistent from the beginning. Of course, the patent invalidation request can be invalid for others or for one's own patent, as the case may be. According to the type of patent to be invalidated, the official fees for general patents will be different. The specific amount is invention 3000, utility model patent 1500 and the same design 1500. The official fee is cheaper, but the way of agency application is different. The amount of agency fee is related to the complexity of the case, and the agency will generally analyze it according to the case. Of course, the patentee should also know that the invalidation of a patent does not mean that it will be directly invalid. If the patentee refuses to accept the decision made by the Patent Office, he can still reply through other channels. Anyone who refuses to accept the decision of the Patent Reexamination Board to declare the invention patent right invalid or maintain the invention right may bring a lawsuit to the court within 3 months from the date of receiving the notice. As for the success of the prosecution, it depends on the patent evidence, and finally the detailed results will be announced by the Patent Office.
