According to a Joint Statement issued by SIPO and DPMA, the Patent Prosecution Highway (PPH) experimental zone was set up on Jan. 23, 2012. This program, unlike the PPH between SIPO and USPTO (United States Patent and Trademark Office), only includes general PPH, but not the Patent Cooperation Treaty PPH. Under this initiative, applicants can file their PPH applications to either SIPO or DPMA.
Applicants who want to file the PPH application to SIPO can visit here for further information (Chinese).
Applicants who want to file the PPH application to DPMA can find further information here (English).
This program will continue for two years and will be due on Jan.22, 2014.
Additionally, SIPO set up the PPH experimental zone with the USPTO on Dec. 1, 2011, which will only continue for one year.
