When is the examination time of invention patent form? With the development of society, in our daily life, we all know that we will apply for a patent for a new product, so we will review it accordingly. I believe many people are not very clear about when the invention form will be reviewed. Let me introduce it to you. When is the examination time of invention patent form? You need to disclose your patent specification before you can find it, provided that you make a request for disclosure in advance, which usually takes 8- 10 months. After the substantive examination fee is paid, it basically enters the substantive examination stage. It doesn't matter when he enters as long as he submits the substantive examination request and pays the money. What matters is when the test results are published, which usually takes at least 1 year. According to the patent law, the patent application will be published after the expiration of 18 months. You can't find your patent on the Internet, because your patent is still confidential. With regard to the patent law, it is said that an application for a patent for invention can be examined in substance within three years from the date of application, and the patent administration department in the State Council can examine its application at any time according to the request of the applicant. Article 35 of the Patent Law Within three years from the date of filing, the administrative department for patent in the State Council may, at any time, make a preliminary examination of the application at the request of the applicant; If the applicant fails to request substantive examination within the time limit without justifiable reasons, the application shall be deemed to have been withdrawn. 6.4. 1 Requirements for the request for substantive examination in Chapter I, Part I of the Patent Examination Guide. The request for substantive examination shall be filed within three years from the date of application (priority date, if any), and the substantive examination fee shall be paid during this period. Because the examination procedure of invention patent is preliminary examination first, and then substantive examination, only after the preliminary examination is qualified can a request for substantive examination be submitted to the Patent Office within three years from the application date (priority date). It means that when examining an application, the patent office should not only examine the formal requirements of the application, but also examine whether the invention in the application meets the substantive requirements such as novelty, creativity and practicality. According to China's patent law, invention patents are subject to substantive examination, while utility model patents and design patents are subject to formal examination. The latter also needs to meet substantive requirements. 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. The main flow of an application for a patent for invention includes: submitting an application-preliminary examination-public stage-substantive examination-patent authorization.
