Priority documents provided via DAS must be available to the NLPO within the period specified in article 9(8) of the Rijksoctrooiwet 1995 (Netherlands Patent Act of 1995). Where a priority document temporarily cannot be retrieved from DAS witl1in the relevant period, and a certificate in accordance with paragraph 13 of the modified Framework Provisions states that the document was available before the end of the relevant period, then the document may be retrieved later with no further action required by the applicant.

If a priority document cannot be retrieved from DAS by the NLPO, and the period specified in article 9(8) Rijksoctrooiwet1995 has not passed, then the applicant may furnish a copy of the document by other means. The NLPO will notify an applicant if it is unable to retrieve a document from DAS.
