NL Online filing at the Dutch Intellectual Property Office The Dutch Intellectual Property Office (hereafter NL IPO) offers online services that allow you to create and to file patents electronically, as well as to create and send other patent-related documents electronically to the NL IPO.

The online services offered by the NL IPO use a software package developed by the European Patent Office (hereafter EPO) called « electronic On Line Filing » (eOLF) via a Dutch server as well as the smartcards issued by the EPO in order to ensure the security of online filing. In this context the NL IPO proposes the following three online filing services:

  • the filing of a Dutch patent application and subsequently filed documents;
  • the filing of documents relating to the validation of a European patent in The Netherlands;
  • the filling of a PCT application and subsequently filed documents
