Are patents filed abroad protected in China?

There are geographical restrictions on patent protection, that is, the patent you apply for in China can only be protected in China, and the patent you apply for in the EU can only be protected in the EU. Therefore, the patent deployment of enterprises needs to be done well before the market planning or synchronized with the market planning.

Based on this characteristic of patents, a technology may correspond to multinational patents. However, patent offices all over the world require applicants to pay annual fees to maintain the validity of patent rights after patent authorization, so applicants need to pay annual fees for a technology in many countries, and the payment time of each patent is still inconsistent.
