Our European Patent attorneys will advise on which strategy to adopt:

  • Request a UP (an EP with unitary effect)
  • Pursue classic EP validation (EPV) 
  • A combination of both
Talk to us to find out what approach suits your needs.

Unitary Patent, European Patent Validations or both?

During the current seven-year transitional period (extendable to 14), EP applicants have the following options:

  • Request unitary effect upon grant of an EP 
  • And / or validate their EP the “classic” way in European Patent Convention (EPC) countries
  • Opt out from the UPC's jurisdiction for specific or all patents (in bulk)

Remember: A combination of both options is possible, i.e., to request unitary effect for your EP while also validating it the classical way in countries that are not covered by the Unitary Patent (e.g., the United Kingdom, Switzerland or Spain).

The coexistence of the earlier EPV system with the new UP / UPC system
offers various strategic opportunities.


Keep your stars out

Opt out your stars (i.e., most valuable patents) from the jurisdiction of the UPC and validate them in key territories for a fine-tuned approach.


Avoid central revocation



Opt out some and leave in some of the stronger as well as the weaker patents for each product family. Pursue a hybrid approach that is more difficult to counter.


Effective dissuasion


Wait and see

Opt out the entire portfolio for the time being and then choose the most appropriate battlefield (UPC or national courts) before initiating lawsuits.


No risk of central revocation, maximizes forum-shopping opportunities


Increased visibility

Request unitary effect for your patents and validate in EPC countries where operation is planned (e.g., the United Kingdom or Spain).


Scope over most EU territories at a reduced cost, a single pan-European action can be implemented
