Different from the vertical management of the Industrial and Commercial Bureau (under the jurisdiction of the Trademark Office), local intellectual property offices are established by local governments, and their administrative levels are not completely unified. Some places have official departments, such as Beijing, Shanghai and Zhejiang. Some places implement the standards of the deputy department level, such as Anhui, Henan and Shanxi.
