Why is there a problem of "no registration category" when applying for CPC client with patent electronic?

Your question can be raised in the online consultation of the patent electronic application network.

Because the patent office software is very unstable, similar inexplicable problems often appear.

If you update the client and reinstall it, there should be no problem.

Patent office. I once criticized them. . . . . . . . . He doubled my patent authorization, and I suggest that they correct me as soon as possible. It would be a pity if Japan saw it. They were also sorry and said, "It's dawn."
