Purpose and Outline of the Patent Prosecution Highway

The PPH enables an application whose claims have been determined to be patentable in the Office of First Filing (OFF) to undergo an accelerated examination in the Office of Second Filing (OSF) with a simple procedure upon a request from an applicant on the basis of bilateral office agreements.

Purpose and Outline of the Patent Prosecution Highway

The purpose of the PPH is to facilitate an applicant's acquisition of a patent at an early stage worldwide and to enhance the utilization of search and examination results between the IP Offices so as to reduce the burden of examination and to enhance the quality of examination worldwide.

The JPO has commenced the PPH programs using the PCT international work products (PCT-PPH) on pilot basis. Under these programs, an accelerated examination can be requested using a written opinion established by certain International Searching Authorities (WO/ISA), a written opinion established by certain International Preliminary Examining Authorities (WO/IPEA) or an international preliminary examination report (IPER) established by certain International Preliminary Examining Authorities. The details of PCT-PPH are here.
