Application routes

The Patent Cost Benefit Guide operates with five application routes. The five routes are drawn up on the basis of the options which Danish companies primarily use.

Application process 1: Your national country (DK here) = > National application (NA)

If you would like to obtain a patent in your national country (Denmark here) plus a few other countries, this could be the right application route for you. When you have filed a national patent application, you have 12 months from the filing date in which to file patent applications in the other countries where you want to obtain a patent.

Application process 2: Your national country (DK here) = > European patent application (EP)

If you would like to obtain a patent in a number of European countries, as well as in your national country (Denmark here), you can start by filing a national application and in that way get an early assessment of your application. Based on the result of that, you can decide whether you want to file a European patent application. You must do so within 12 months from the date when the national application was filed.

Application process 3: Your national country (DK here) = > International application (PCT) = > EP, NA, NA

If you would like to obtain a patent on your invention in many countries in addition to your national country, you can start by filing a national patent application and continuing it through the PCT system. You must file an international patent application within 12 months from the filing date in your national country. It must then be extended as national applications and/or as a European application.

Application process 4: European patent application (EP)

If you wish to obtain a patent in a number of European countries, you can file a European patent application directly with EPO. The European patent application will be processed and granted centrally by EPO.

Application process 5: International application (PCT) = > EP, NA, NA

If you wish to obtain a patent in many countries, you can file an international application directly with an international patent authority. This application must then be extended as national applications and/or as a European application.

EPO

Most European countries have acceded to the European Patent Convention (EPC) and by doing so are EPC countries and members of the European Patent Organization. This means that the European Patent Office (EPO), which is a regional patent office in Europe, can issue patents with effect for all these countries.

The Patent Cooperation Treaty (PCT)

The Patent Cooperation Treaty (PCT) has been established to facilitate access to obtaining patents in many countries and currently includes 142 countries, including Denmark.
