In two separate announcements in January 2009, the USPTO indicated that the Korean Intellectual Property Office (KIPO) will participate in the Patent Prosecution Highway (PPH) on a full-time basis, and the Intellectual Property Office of Singapore (IPOS) will participate in a trial initiative of the PPH.
Under the Patent Prosecution Highway (PPH), applicants who receive a ruling that at least one claim of an application is patentable, in the U.S. or Korea, for example, can request that the corresponding application in the other office receive expedited treatment.
