My solution is to go to/tooldown/index.jhtml.
The patent electronic application website of the State Information Bureau downloaded the CPC client offline upgrade package (20 13-09-02) supporting windows7 operating system and office2007 version, and then it was solved. I am win7 Home Edition, and the installed word2003 is pirated. At first, I suspected that it was a text problem, so I reinstalled it once and it was not solved.
In addition, I also have some doubts about the specific steps of reply and correction, but it should be the one you said. There are two buttons "New" and "Modify" when making corrections. To be on the safe side, I always use "new" because there is nothing wrong with the previous revision. Dare not use "modify".
I hope it helps you.
