What kinds of patent specifications are there?

It is not only a technical document describing the details of each invention and creation for which a patent is applied, but also a legal document reflecting the type of patent right and the legal status of its application. Due to the different types of patent rights stipulated in the patent laws of different countries and the different patent examination and approval systems in different countries, various patent specifications have been produced. According to the types of patent rights, the patent specifications published by various countries include: invention patent specifications, utility model patent specifications (designs are not published separately, but all countries report them in the patent gazette), plant patent specifications, supplementary patent specifications, re-published patent specifications, patent specifications for case applications, improved patent specifications, inventor certificate specifications, and economic patent specifications. According to the legal status, the patent specification includes: those that have not been examined (only substantive examination) and have not yet approved the patent, such as the British patent application specification, the Japanese public charter bulletin, the China invention patent application disclosure specification, and the China utility model patent application specification; Explanations that have been examined but not approved, such as those exhibited in the Federal Republic of Germany and those examined and approved by China's invention patent application; Patent specifications that have been examined and approved, such as American patent specifications and European patent specifications; Patent specifications approved by novelty examination, such as French patent specifications; Unapproved patent specification, such as the patent specification of old France (patent law before 1969). In addition, due to the continuous development and changes of the patent system, some countries have produced some special kinds of patent specifications. For example, France has increased the protection of medical inventions in 1948 and 1960.
