What is the reason for the unsuccessful patent application?

Many individual intellectual property patent applications have not been successful for several years, but some people's patents will be granted soon. Why is this? What is the reason for the unsuccessful patent application? What is the reason for the unsuccessful patent application? First of all, patents are divided into three categories: invention patents, utility model patents and design patents. The patentee has the right to manufacture, use, promise to sell, sell, import, transfer and license the patent. If a non-patentee wants to use the patented technology of others, he must obtain the consent or permission of the patentee according to law. Secondly, the main procedures of patent application include: preliminary examination and announcement, substantive examination and grant of patent right. 1. Preliminary examination and announcement: After receiving an application for a patent for invention, the patent administration department of the State Council, after preliminary examination, finds that it complies with the relevant laws and regulations, and shall publish it 18 months after the date of application. The patent administration department of the State Council may publish its application at an early date upon the request of the applicant. 2. Substantive examination: A. Within 3 years from the date of filing, the patent administration department of the State Council may conduct substantive examination of the application at any time. If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. The patent administrative department of the State Council may, when it deems it necessary, examine the application for a patent for invention on its own. Patent applications for utility models and designs can be authorized without substantive examination. 3. Grant of patent right: If the application for a patent for invention has undergone substantive examination and the application for a patent for utility model and design has undergone preliminary examination, and no reason for rejection is found, the patent administration department in the State Council shall make a decision to grant the patent right for invention, utility model and design, issue the corresponding patent certificate, and register and announce it at the same time. The patent right shall take effect as of the date of announcement. Finally, why do many individuals fail to apply for patents repeatedly? It turns out that individuals applying for patents can apply for patents directly by mailing relevant application materials to the China National Intellectual Property Administration Patent Office, or they can apply for patents through qualified agencies. However, due to many problems such as incorrect information, unprofessional expression or unclear description, many applications may have to be revised several times to meet the requirements.
