What should I do if my patent expires?

Can I apply for restoration after the patent expires? (1) If a party delays the deadline due to irresistible reasons, resulting in the loss of rights, it may, within 2 months from the date when the obstacle is removed, or at the latest within 2 years from the date when the deadline expires, explain the reasons to the Patent Office and attach relevant supporting documents to request the restoration of rights; (2) If the party concerned delays the deadline for justifiable reasons, resulting in the loss of rights, he may explain the reasons to the Patent Office within 2 months from the date of receiving the notice from the Patent Office and request the restoration of rights; (3) Those who fail to pay the maintenance fee or annual fee on schedule can only request the Patent Office to restore their rights on irresistible grounds. The above contents are related answers. If the patent right expires, you can resume the application, but if for some reason, such as something irresistible or something important, you still have the patent right expired, and you can't get out. As the most effective carrier of technical information, patent literature contains more than 90% of the latest technical information in the world, which is 5-6 years earlier than the information provided by general technical publications. Moreover, 70%-80% of inventions are only disclosed through patent documents, which are not found in other scientific and technological documents. Compared with other literary forms, patents are more novel and practical. It can be seen that patent literature is the largest technical information source in the world. According to empirical statistical analysis, patent literature contains 90%-95% of the global scientific and technological information. Such a huge information resource is far from being fully utilized. In fact, for enterprise organizations, patents are the only place where competitors have to disclose some key information to the public, and these information will not be disclosed elsewhere. Therefore, the analyst of enterprise competitive intelligence can get a lot of useful information from patent literature through careful, rigorous, comprehensive and relevant analysis, so that the published patent information can be used by enterprises and realize its unique economic value. Consulting patent documents frequently in scientific research can not only improve the research starting point and level of scientific research projects, but also save about 60% of research time and 40% of research funds. In China, a patent has two meanings: 1, and its colloquial use only means "exclusive". For example, "This is just my patent". 2. There are three confusing meanings in intellectual property rights, including: first, the patent right refers to the patent right enjoyed by the patentee, that is, the state grants the patentee or his successor the exclusive right to use his invention and creation within a certain period of time, and the emphasis here is on rights. Patent right is an exclusive right with exclusivity. If a non-patentee wants to use the patented technology of others, he must obtain the authorization or permission of the patentee according to law. Second, it refers to inventions protected by the patent law, that is, patented technology, which is a proprietary technology recognized by the state and protected by law on the basis of publicity. The "patent" here refers to the technology or scheme protected by national laws. The so-called proprietary technology is the technology with exclusive rights, which is a bigger concept, including patented technology and technical secrets. Some professional technologies that do not belong to patents and technical secrets are meaningful only in some technical service contracts. ) A patent is an invention protected by legal norms. It is an invention that submits a patent application to the national examination and approval authority, and after passing the examination according to law, the patent applicant is granted the exclusive right to the invention within the time specified by the country, and the annual fee needs to be paid regularly to maintain the protection status in the country. Third, it refers to the patent certificate issued by the Patent Office to confirm that the applicant enjoys the patent right for his invention-creation, or refers to the patent document that records the content of the invention-creation, and refers to the specific material document. The relevant provisions of patent right are set to protect the basic rights and interests of patent inventors, which is conducive to protecting their rights and stimulating people's enthusiasm for invention. If your patent has expired, you can apply for patent restoration as long as you meet these three conditions stipulated by law, so don't worry too much about these things.
