Patent Prosecution Highway (PPH)

Urban traffic light effects symbolizing connectivity

The Patent Prosecution Highway (PPH) allows the sharing of work products by the participating offices. This enhances efficiency of the patent examination process – thereby increasing user-friendliness – and improves examination quality.

In order to request accelerated examination under the PPH, it is required that a corresponding application has been filed with a PPH partner office and that the PPH partner office has found at least one patent claim patentable. In such a case, the offices exchange their work products and search results for mutual use without being bound by prior work products.
Participation in the PPH is free of charge at the DPMA.

The DPMA and its partner offices

The Global Patent Prosecution Highway (GPPH) is a multilateral pilot programme in which all national and regional patent offices can take part. Besides the DPMA, 23 other patent offices are involved in the GPPH (status: 6 July 2017).
Since the China National Intellectual Property Administration (CNIPA) is not part of the GPPH network, the DPMA has a bilateral PPH pilot with CNIPA.
Applicants can thus file a PPH request with the

  • China National Intellectual Property Administration (CNIPA)

as well as with the following offices within the GPPH framework:

  • Austrian Patent Office (APO)
  • Canadian Intellectual Property Office (CIPO)
  • Danish Patent and Trademark Office (DKPTO)
  • Estonian Patent Office (EPA)
  • Federal Service for Intellectual Property of the Russian Federation (Rospatent)
  • Finnish Patent and Registration Office (PRH)
  • Hungarian Intellectual Property Office (HIPO)
  • Icelandic Patent Office (IPO)
  • Intellectual Property Office of New Zealand (IPONZ)
  • Intellectual Property Office of Singapore (IPOS)
  • Intellectual Property Office of the United Kingdom (UK IPO)
  • IP Australia
  • Israel Patent Office (ILPO)
  • Japan Patent Office (JPO)
  • Korean Intellectual Property Office (KIPO)
  • Nordic Patent Institute (NPI)
  • Norwegian Industrial Property Office (NIPO)
  • Patent Office of the Republic of Poland (PPO)
  • Portuguese Institute of Industrial Property (INPI)
  • Spanish Patent and Trademark Office (SPTO)
  • Superintendence of Industry and Commerce of Colombia (SIC)
  • Swiss Federal Institute of Intellectual Property (IPI)
  • United States Patent and Trademark Office (USPTO)

Benefits of the GPPH

The PPH requests can be made under the same requirements for all patent authorities involved in the GPPH. This makes use of the PPH easier and thus more attractive for the applicants.
Another significant new feature is the fact that positive PCT opinions (written ISA or IPEA opinion and international preliminary examination report) of an authority participating in the GPPH pilot can also be the basis for a PPH request. A PPH request at the DPMA can therefore now be based on a PCT work product of a partner authority.
Applicants at the DPMA do not have to wait for the decision to grant a patent. Rather, they can make a request for accelerated examination at any partner office involved in the GPPH on the basis of a search report in which the DPMA has found all claims to be allowable. They can thus faster receive the office action of the partner office.

The request form and other forms for participation in the Global PPH pilot as well as the detailed requirements are available under forms.

The work products of the patent authorities participating in the GPPH on which a PPH request can be based within the framework of the GPPH is listed in pdf-Datei Annex F.
