PPH provides an accelerated examination of a patent application, when another collaborating patent authority has already carried out a patentability assessment for the same invention.

Benefits of using the PPH system

The PPH speeds up the examination process, enabling it to start at a more informed level than is otherwise the case. Nor is it necessary for the patent authority to enter into so much correspondence with the applicant, which again leads to lower costs. A PPH ensures greater predictability concerning the outcome of the application, and a decision can be reached faster.

For patent authorities PPH means less duplication of work and more effective examination procedures. It also contributes to improving the quality of patentability assessments and reducing the backlog of patent applications.

More about PPH

A PPH agreement allows a patent applicant to request an accelerated examination of the application, if a favourable report has already been received for corresponding claims from a previous patent authority.

The second authority may then reuse these search and examination results. This enables the second authority to carry out a faster examination of the application because the process can start at a more informed level than is otherwise the case. An independent national examination will however still be carried out according to national legislation and practice.

PPH is voluntary for patent applicants. No fee is charged in Norway.


Favourable reports from national authorities may be used by international PCT authorities and vice versa (for example Nordic Patent Institute). NIPO is not an international authority (only a receiving Office). Our search reports in international PCT applications will therefore normally arrive too late for them to be used as a basis for GPPH. However, reports from Nordic Patent Institute may be used as they are available earlier.


Due to increased globalisation, there is a growing need for applicants to be able to apply for a patent for the same invention in several countries at the same time. This means that patent authorities all over the world often carry out parallel examinations.

PPH was established to meet the applicant’s need for an accelerated examination process, while at the same time enabling patent authorities to cooperate with each other to ensure the quality and effectiveness of examination procedures.
