My initial reaction to the above question was yes. However, consider the following - if DE, JP and KR have problems with earlier applications, is the second PCT considered to supersede the first? Does a second PCT automatically mean that the first PCT is deemed withdrawn in these countries? The Euro-PCT guide seems to suggest it is automatic, irrespective of new subject-matter.
“According to the national law of these states, the filing of an international application which contains the designation of that state and claims the priority of an earlier national application filed in that state (for Germany: for the same kind of protection) will have the result that the earlier national application ceases to have effect, with the same consequences as the withdrawal of the earlier national application”
I'm not asking for the community to look all this up, I just wanted to demonstrate that I have given this thought and would like an opinion from those here.
