What are the better patent application agencies in China?

Domestic applicants are Hong Kong Li Anrui Intellectual Property Group, Beijing Unitalen Intellectual Property Agency Co., Ltd. and China Patent Agency (Hong Kong) Co., Ltd. . . . . Both are good, and the number of patent applications ranks first in the country. The key is that you should make some requirements yourself, or ask to read the manuscript before sending it to the official to see if it is done well. In fact, whether the examples in the manual are fully open (as many as possible, you provide more alternative examples yourself) and whether the deployment of claims is reasonable (layered protection) is the key.
