Online filing at the Luxembourg Intellectual Property Office

The Luxembourg Intellectual Property Office (hereafter LU OPI) 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 LU OPI.

The online services offered by the LU OPI use a software package developed by the European Patent Office (hereafter EPO) called "electronic On Line Filing" (eOLF) via a Luxembourg server as well as the smart cards issued by the EPO in order to ensure the security of online filing.

In this context, the LU OPI offers you the following online filing services:

  • the filing of a Luxembourg patent application;
  • the filing of documents produced after the filing of a Luxembourg patent application or the grant of a Luxembourg patent.
