About PPH

The PPH scheme is a cooperation agreement between patent authorities concerning use of each other's statements on patentability, in their own assessment.

PPH has been devised to meet the needs of patent applicants for faster processing of applications, as well as the wish of the patent authorities to cooperate more in order to ensure quality and efficiency in the processing of patent applications.

PPH processing allows a patent applicant to request faster processing of his application by a patent authority, when a previous patent authority has already found the corresponding claims to be patentable. PPH processing can only be done on the basis of a patentability assessment made by a cooperating patent authority; an assessment from other patent authorities cannot be used.

When PPH processing is carried out, any searches or assessments that have already been done, will be used further in the process. An independent national examination will however still be carried out according to national legislation and practice.

The Norwegian Industrial Property Office aims to start case processing and send the first written opinion within 3 months after the application for PPH processing has been submitted.

In an application for PPH processing, the patent claims must be equivalent to or narrower in scope than the claims assessed by the other patent authority as patentable. If we have already started processing an application, the PPH scheme can not be used.

There is no fee for PPH in Norway.
