Get the most out of the new European patent system


With the entry into force of the Unitary Patent (UP) and the Unified Patent Court (UPC),
EP applicants are confronted with new choices that - while presenting great opportunities - also entail risks that should not be overlooked.

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

  • Request an EP with unitary effect
  • Validate a classical EP 
  • Or a combination of both
Talk to us to find out what approach suits your needs.

Unitary Patent, European Patent Validations or both?

During the seven-year transitional period (extendable to 14) that starts from Germany´s ratification of the UPC agreement, EP applicants will have the following options:

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

Discover your options for the sunrise period.

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

Sunrise period

Once Germany ratifies the UPC Agreement, the so-called sunrise period of a minimum of three months starts.
During this period, Dennemeyer offers the following services:

Sunrise Period_update
  • Opt-out individually or in bulk the EPs of your choice (published or already granted).
Benefit from our bulk opt-out discount during the sunrise period!

  • Request a delay in issuing the publication of the mention of grant of a European patent (Rule 71(3) EPC).

    ->  available from January 1, 2023 (despite the postponement of the sunrise period)

Ensure that the unitary effect of your EP patent shall be registered on day 1 of the UPC.

  • Request early unitary effect
    ->  available from January 1, 2023 (despite the postponement of the sunrise period)

Ensure that the unitary effect of your EP shall be required before the UPC starts.


The coexistence of the current EP validation (EPV) system with the new UP / UPC system
offer various strategic opportunities.


Keep your stars out

Keep your stars (i.e., most valuable patents) out of the UPC's jurisdiction. Opt out your most valuable EPs during the sunrise period.


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 (early) unitary effect for your patents, 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.
