What's the difference between Zhengzhou Patent Office and Henan Intellectual Property Office? Is business different? thank you ...

Zhengzhou Patent Office is not only a subsidiary of Henan Intellectual Property Office, but also responsible for patent application. In addition to patents, the Henan Intellectual Property Office is also responsible for trademark registration and copyright registration. Business is not just a simple patent office. That's all I know. I hope I can help you.
