Foreign patents are not protected domestically. If you want to transfer it, the procedures can only be completed in the country where the patent is located. Domestic companies can only use the patent in this country after obtaining it. If you have applied for a patent in a foreign country and want to obtain patent protection in China at the same time, you should apply for a domestic patent based on the priority of the foreign patent. After authorization, you can apply for a Chinese patent.
Hope this is helpful to you
