Patent agency in different places

The main problem is communication. If the technology is complicated, you can't communicate with technicians face to face, and you can't see the real product, which may have a certain impact on writing.

Another problem involved is that some policy issues in patent applications in different regions, local institutions will be more aware of local government policies, such as funds, high technology and so on.
