30. August 2019 – News UPC Germany: No ratification of UPCA as long as consequences Brexit are not known

The German Federal government will not proceed with ratification of the UPCA until the consequences of the Brexit are confirmed. In a letter this August the German Justice Ministry stated:

“The issue of the withdrawal of the United Kingdom from the European Union (so-called Brexit) and its implications for European patent reform play an important role in the further implementation process of the Unified Patent Court Agreement. The real and legal implications of withdrawing must be examined with regard to the Agreement and agreed at European level. This opinion forming is currently not finalized, not least because significant factors of the expected exit are not yet known.”

The letter from the German Justice Ministry comes as a constitutional complaint against the UPCA and is expected to be heard before the German Federal Constitutional Court later this year or at the beginning of 2020.

The Unitary Patent system has already suffered delays due to the constitutional complaint. It remains to be seen how the letter from the Justice Ministry will affect the ratification process and the outcome of the constitutional complaint.

5. April 2019 – BREXIT and the consequences for owners of patents, trademarks and designs

The UK's withdrawal from the European Union without contractual arrangements on 12 April 2019 (or later), the so-called hard BREXIT, will have serious consequences for owners of Intellectual Property rights. The same applies to a regulated BREXIT which would become effective on 31 December 2020 (or any other date to be agreed). We recommend to all owners of patents, trademarks and designs who are dependent on maintaining their rights in the UK:

Check your portfolio now and make appropriate provisions.

Monitor the further developments frequently. We are happy to assist you!

In summary, one can say that owners and licensees of patents - to the present state of knowledge - can rely on the continued validity of existing legal regulations.

Owners of trademarks and designs, who need an extensive protection in the UK, should now act and verify a preventive national application in the UK.
