Chinese and German offices extend Patent Prosecution Highway (PPH) pilot

Since 23 January 2012, patent applicants have been able to request accelerated examination of their applications at the German Patent and Trade Mark Office (DPMA) and at the China National Intellectual Property Administration (CNIPA). This option will continue to be available. The DPMA and CNIPA have extended the pilot programme's duration by a further three years until 22 January 2027.

The PPH allows the applicant to file a request for accelerated examination as soon as at least one patent claim has been found to be patentable by the partner office. The DPMA will then carry out an independent search on the basis of the partner office's work results. The applicant benefits from the sharing of work results between the offices. This can even further expand prior art search.

The DPMA has had a long-standing and close cooperation with CNIPA. In addition to the bilateral PPH agreement with CNIPA the DPMA takes part in the Global PPH pilot, in which 27 offices in total are participating.

More information on the PPH programme with CNIPA is available here.
