Use Sim’UP to simulate scenarios and help in decision making for the validation of your European Patents

This completely free online tool – developed by REGIMBEAU – enables you to perform budget simulations and compare the post grant costs of your European Patents (EP), with or without the Unitary Effect.

The proposed estimates include the official fees as well as professional fees for the following steps:

  • validation (including possible translation costs);
  • payment of renewal fees.

The tool takes June 1st, 2023 as the application date of the Unitary Effect in 17 countries (i.e. the countries that have ratified the agreement - Austria, Belgium, Bulgaria, Denmark, Estonia, Finland, France, Germany, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Portugal, Slovenia, Sweden).
The simulation tool parameters, including the official fees, were last updated on March 2, 2023

What is the Unitary Patent?

The Patent system in Europe will undergo major changes with the entry into force of the agreements establishing the Unified Patent Court (UPC) and the Unitary Patent system (UP) on June 1, 2023. Choosing to validate a European Patent with Unitary Effect will enable a single European patent to be enforceable in each and every EU country where the Unitary Effect is applicable, i.e. in at least 17 countries. Bearing in mind that such Unitary Effect is not available should the patentee elect to opt-out from the exclusive competence of the Unified Patent Court, the costs and abandonment strategy are key factors in deciding a validation strategy.
