IP5 PPH


Outline

The five largest intellectual property offices in the world (IP5 Offices) - JPO (Japan), CNIPA (China), EPO (Europe), KIPO (South Korea), and USPTO (USA) - started an IP5 PPH pilot program, on January 6, 2014, that made three types of PPH (Normal, MOTTAINAI, and PCT-PPH) available among the five Offices.

The IP5 Offices developed a model common PPH request form and provided instructions regarding the common structure of the request forms adopted by IP5 and differences in some sections of those forms.
