According to Memoranda of Understanding between China’s State Intellectual Property Office (SIPO) and the Industrial Property Institute of Chile (INAPI), and SIPO and the Industrial Property Office of the Czech Republic (IPO-CZ), both combinations will start a Patent Prosecution Highway (PPH) pilot on 1 January 2018. The Sino-Chilean pilot will end on 31 December 2020 and the Sino-Czech pilot on 31 December 2019.
A PPH can speed up the patent examination process, because the affiliated countries do not have to do the search, examination etc twice. The Japanese have a nice term for a sense of regret concerning waste if a resourc is not property utilized: MOTTAINAI. So MOTTAINAI can be avoided with a PPH.
See the announcement on the SIPO site here (Chinese), and on how applicants can make a PPH request, electronically at the Patent Office reception desk, here.
