Request for invalidation of utility model patent right: 1500 yuan. Request fee for invalidation of design patent right: 1500 yuan. All the above are the official expenses of the request for invalidation. According to national regulations, it is necessary to pay fees. If you are looking for an agency to apply for patent invalidation for you, then you need to pay the agency fee. Examination procedure for invalidation The invalidation shall be accepted and examined by the Patent Reexamination Board (hereinafter referred to as the "Reexamination Board"), which has different examination departments according to different technical fields. Invalid requests will be divided into departments according to the field, and all departments will set up a collegiate bench to review them in chronological order. Due to different cases in different fields, the review cycle of invalidation will be quite different. In general, the longest examination period for invention patents is about 2-3 years, followed by 0.5-2 years for utility models, and the appearance examination period is short, generally 0.5- 1.5 years. In addition, if there is a patent ownership dispute in the process of invalid examination, the invalid examination can be suspended and the period of invalid examination can be further extended. Except for particularly simple cases, there is usually an oral review procedure in the invalid review procedure, which is similar to the court trial procedure. Both parties make oral statements under the auspices of the collegial panel, and generally will receive an invalid review decision about 3-5 months after the oral review procedure.
