my country’s Patent Law stipulates that if the Patent Office determines after preliminary examination that an invention patent application complies with the provisions of this law, the application shall be published 18 months from the date of application. The so-called early disclosure refers to the date of application for an invention patent, or the date of priority if it has priority. Applicants can request early disclosure of their patent applications and should submit an early disclosure statement. An advance public declaration can immediately enter the disclosure process after passing the preliminary review by the Patent Office. An advance public declaration is only applicable to invention patent applications. The applicant cannot attach any conditions to the advance public declaration. For applicants, the advantage of early disclosure of an invention patent is that according to the provisions of the Patent Law, after the invention patent application is published, the applicant can require the unit or individual who implements the invention to pay appropriate fees, which is to obtain the so-called "temporary protection." By publishing the application as early as possible, the applicant can obtain temporary protection under the Patent Law as early as possible. In addition, early announcement may help the patent enter the market and occupy the market in the future. The disadvantage is that if the application content is disclosed too early, others may take advantage of the application, which may harm the interests of the applicant. In addition, for withdrawn patent applications, there is a big difference between published and unpublished patent applications. If the content of the application has not been disclosed, the technology can still be owned by the applicant as a technical secret, and a new patent application can be filed in the future; if the content of the application has been disclosed, it means that the technology has entered the field of publicly known technology, and the applicant cannot Then obtain patent protection for the same content. Applicants often want this disclosure to be later in order to have more time to make a final decision on whether to disclose their technology or to prepare for the disclosure of the technology. From a public point of view, the early publication of invention patents is conducive to the dissemination of the latest technology; it avoids repeated research and reduces unnecessary waste of manpower, material and financial resources; it is possible to research and develop newer products as early as possible under the inspiration of other people's inventions. More advanced technology.
