For applicants, the advantage of early disclosure of invention patents is: according to the patent law, after the invention patent application is published, the applicant can require the unit or individual who implemented the invention to pay appropriate fees, that is, Obtain what is 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: 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 In addition, for withdrawn patent applications, there is a big difference between published and unpublished patent applications.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.
