Does it have to be the same to apply for domestic patents abroad?

It must be the same. According to official website of the Patent Office, applying for a domestic patent abroad requires the same content. When applying for a foreign patent, the applicant should first file a patent application with the China Patent Office, and only after the application is approved can he directly apply for a foreign patent. Patent refers to inventions protected by the patent law, that is, patented technology, which is a proprietary technology recognized by the state and protected by law on the basis of publicity.
