找到一个东西这样说的：
Convergence of Chapter I and II procedures
but Chapters I and II remain legally distinct
International preliminary report on patentability (IPRP) for every application
Chapter I: IPRP = written opinion by ISA
Chapter II: IPRP = IPER
Main difference
Chapter I: no applicant/examiner dialogue or amendments before IPRP issuance
Chapter II: dialogue with examiner and amendments possible before IPRP issuance |
