First of all, in the process of changing patent applicants, users need to pay a handling fee, which is 200 yuan. If the user doesn't notice this kind of fee in the process of making relevant changes, such as not paying the fee within one month after submitting the application, then the change will not be completed, and the applicant will be revoked thereafter.
Apart from the related costs, will there be some factors that affect the change of patent applicants in other aspects? There are not many other influencing factors, but some technological problems need attention. For example, without these kinds of declarations, it is impossible to complete the corresponding changes, and there are still many materials involved, including the written explanation of the ownership and transfer of the patent by the applicant and the patentee, as well as the procedures of signing and sealing by all parties. If there is any deviation, more information is needed to prove it.
Therefore, when the patent applicant changes, the complexity is still high. If users don't know this kind of information and need to do it in a short time, what should patent applicants do to change it? At this time, we can find some intellectual property service platforms to help users make corresponding changes. There are many such platforms. For example, the intellectual property platform is one of them. On this platform, we can not only help users to change patent applicants, but also help users to complete patent applications, annual fees and design applications.
