PCT-PPH

The JPO launched the Patent Prosecution Highway using PCT international work products (PCT-PPH) on 29 January 2010.

In this scheme, examination under PPH can be requested using a written opinion established by a certain International Searching Authority (WO/ISA) or a written opinion or international preliminary examination report established by a certain International Preliminary Examining Authority (WO/IPEA or IPER).
