How long has the patentee changed?

Legal analysis: According to the relevant provisions of China's patent law, there are detailed provisions on the time when the patentee changes. Patent change, commonly referred to as filing project change, refers to some information of the patent, such as information of the obligee, inventor and agency. If you want to change, you need to make a statement to record the change of the project. The general rule is 15 to 30 days. Of course, some special circumstances are not ruled out, and it may take more than a month.

Legal basis: Article 46 of the Patent Law of People's Republic of China (PRC). The Patent Reexamination Board shall promptly examine the request for invalidation of the patent right and make a decision, and notify the claimant and the patentee. The decision to declare the patent right invalid shall be registered and announced by the patent administration department of the State Council. Anyone who refuses to accept the decision of the Patent Reexamination Board to declare the patent right invalid or maintain the patent right may bring a lawsuit to the people's court within three months from the date of receiving the notice. The people's court shall notify the other party to the procedure for requesting invalidation to participate in the proceedings as a third party.
