What's the difference between China Patent Office and China National Intellectual Property Administration Patent Office (Examination and Cooperation Center)? Is it a unit?

Both of these units belong to China National Intellectual Property Administration. The development company was established in 1986, and its initial business was patent promotion. The trial association was established at 0 1 with the initial purpose of eliminating the backlog of cases.

In 2006, the development company was entrusted by the State Information Bureau to start the data deep processing business, and all the classification departments of the audit association were placed under the development company. Therefore, some people think that it is a subordinate relationship, but it is actually two parallel relationships. The development company is a state-owned enterprise and the audit association is a public institution.
