How to inquire about foreign patents

Legal analysis: The effective method is to search for patent application and authorization on the official website of foreign intellectual property offices or organizations, and at the same time, you can also retrieve the full text of the application documents. Patents protect their exclusivity by law in exchange for patent disclosure, so all patents that pass the examination should be made public, in other words, they can be downloaded from patent websites.

Legal basis: Article 9 of the Detailed Rules for the Implementation of the Patent Law of People's Republic of China (PRC). After receiving the request submitted in accordance with Article 8 of these Rules, the patent administration department in the State Council considers that the invention or utility model may involve national security or vital interests and needs to be kept confidential, and shall promptly issue a notice of confidentiality review to the applicant; If the applicant fails to receive the notice of confidentiality review within 4 months from the date of submission of his request, he may apply for a patent for invention or utility model abroad, or submit an international patent application to the relevant foreign institutions. Where the patent administration department of the State Council notifies the confidentiality review in accordance with the provisions of the preceding paragraph, it shall make a decision on whether confidentiality is necessary in time and notify the applicant. If the applicant has not received the confidentiality decision within 6 months from the date of filing the request, he may apply for a patent for the invention or utility model abroad, or submit an international patent application to the relevant foreign institutions.
