The PCT-PPH allows the applicant to request PPH based on PCT international work products including ISR and IPER.
Difference from Normal PPH
Although the Normal PPH also allows the applicant to request PPH for a PCT application in the national phase (see the figure below), the Normal PPH requires a national office action assessing the patentability of a corresponding application.
Since a PCT-PPH request is based on PCT international work products, the applicant can request PPH as soon as a PCT application enters the national phase and obtain a patent even faster.
