Are German patents protected in China?

Patent protection is regional and can only be effective under different legal systems. Literally speaking, German patents should be patents filed in Germany or in the European Patent Office. If the patent application is filed only in Germany, but not in China or other countries, then the patent can only be protected in Germany, and certainly not in China. However, it is not excluded that most patent cooperation treaties and relevant laws stipulate that the priority of patent application is 12 months. You can apply for a patent in any other country within 12 months after German application, that is to say, you can become a patent in China within 12 months, or apply for PCT directly, or you can obtain patent protection by designating China as the country of entry within 30 months.
