How many patent offices are there in Chengdu? How many patent agents? thank you

Details can be found on the All-China Association of Agents. There are many firms in Chengdu now, but there are basically 20 with patent practice qualifications. The bigger ones are Jiuding, Hongqiao and Hangzhou, while Ce Tian and Fan Chao are mainly trademarks. As far as agents are concerned, there are not many certificates in Chengdu, the big ones are relatively more, and there may be three or four other small ones. Details can be found directly on the website of the All-China Association of Agents.
