What does the patent announcement include?

Invention patent bulletin, utility model patent bulletin and design patent bulletin are one of the patent documents published regularly. These three announcements have been published since September 1985, and they are all monthly. Since 1990, the three issues of the bulletin have been changed into weekly magazines according to international practice, published every Wednesday, with 52 issues a year and one volume a year. 1985 is the first volume, and so on. The volume number is followed by the issue number, indicating the publication week of the bulletin. For example, Volume 13,No. 10, represents the bulletin published in week 1997. Patent Bulletin Patent Bulletin is the main reference book for searching patent documents in China, the latest patent information in China and the business activities of patent examination in China Patent Office. The contents published in the three patent bulletins can be roughly divided into three parts: the first part publishes or announces the patent application and authorization decision; The second part is the announcement of patent affairs; The third part is the index. The first part publishes or announces the descriptive items, abstracts and abstract drawings recorded in the application for a patent for invention and the application for a patent for utility model. Description items include the name of the application, international patent classification number, application date, application number, publication number or authorization announcement number. The publication of the utility model patent bulletin is the authorization announcement. However, the announcement of invention patent authorization only contains descriptive items. In addition to the description items, the announcement of the design patent bulletin also includes various views or photos of the design, as well as a brief description, and there is no special volume. China joined the Patent Cooperation Treaty (PCT) on 1994, and the China Patent Office became the acceptance bureau of PCT applications, the international search unit designated by the General Assembly of the International Patent Cooperation Treaty Union and the international preliminary examination unit, and the descriptions of international applications were added to all invention patent bulletins. The second part is patent affairs. Record matters related to patent application review and patent legal status. Such as withdrawal of application, revocation of patent right, invalidation of patent right, termination of patent right, inheritance or transfer of patent right, etc. Due to the different examination methods of the three patents, the patent affairs are slightly different. The third part is the index. In this part, the patent applications and authorized patents published in each bulletin are arranged into three indexes according to IPC (International Patent Classification Number), patent number and patentee, and the comparison table of authorization announcement number/patent number is given. It should be noted that the indicators before 1993 are arranged in different ways.
