Secondly, the international exhibition recognized by the China government should refer to the international exhibition registered or recognized by the Bureau of International Exhibitions as stipulated in the Convention on International Exhibitions, which is very important after the third revision of China's patent law. After the legal reform, China implemented the standard of absolute novelty. According to this new standard, it is necessary to judge whether this international exhibition has been recognized by the government of China. On this issue, the first paragraph is added to Article 30 of the Detailed Rules for the Implementation of the Patent Law revised by 20 10. An international exhibition recognized by the China government as mentioned in Item (1) of Article 24 of the Patent Law refers to an international exhibition registered or recognized by the Bureau of International Exhibitions as stipulated in the Convention on International Exhibitions. For example, the world expositions held in its member countries, such as great exhibition of the works of industry of all nations, the first World Exposition held in London in 185 1 year, and the Shanghai World Exposition held in China in 20 10/year. The conditions for registration or accreditation of international exhibition bureaus are very harsh, so the number of such "international exhibitions" is very limited. For those products exhibited in the "International Exhibition Not Recognized by China Government", we should carefully consider whether the exhibition behavior will affect the novelty.
3. In international exhibitions hosted or recognized by the government of China, publications introducing exhibits also enjoy the novelty grace period stipulated in this article. Because it is very common to distribute publications, written materials and display objects, photos and pictures at exhibitions, if only the influence of the exhibition itself on novelty is excluded, but other related behaviors of introducing products are not excluded, then this kind of "temporary protection" will lose its significance. However, it should be noted that publications issued outside the exhibition or publications unrelated to the exhibits at the exhibition, if they have descriptions of technical contents that can damage novelty, belong to the existing technology stipulated in Article 22 of the Patent Law, and therefore do not enjoy the provision of "temporary protection" in the first paragraph of Article 24 of the Patent Law.
Finally, within the six-month grace period for novelty, this disclosure can occur many times, that is, the act of re-disclosure will not destroy the novelty of the invention-creation, but the six-month grace period is calculated from the date of the first disclosure of the invention-creation.
