The Patent Prosecution Highway (PPH) is an initiative which provides a means of significantly accelerating examination of your patent application if examination work has already been conducted at another patent office.
Under the PPH program, if the claims of your application have been found to be acceptable by a first patent office, you may request accelerated examination of a corresponding application at a second office. The PPH is a procedure whereby patent offices can make use of relevant work already conducted by another office when conducting the patent examination.
With effect from 1 October 2014, MyIPO starts a pilot PPH/PCT-PPH programs with the Japan Patent Office (JPO):
i). MyIPO-JPO PPH pilot program
