18. December 2019 – Patent examination in China: Adaptation of CNIPA guidelines

By November 1, 2019, some changes to the guidelines for patent examination in China by the CNIPA (China National Intellectual Property Administration) came into force.

One of the adaptations is the possibility for applicants to request a delayed examination of patentability. This rule applies to patents and designs, but not to utility model applications.

In the case of a patent application, the request for delayed examination shall be made at the time of the request for substantive examination. In the case of a design application, the request must be filed at the time of filing the design application. The examination may be delayed by 1, 2 or 3 years from the date on which the application takes effect.

For the patent application, this procedure can have the advantage that the applicant can adapt the scope of protection for a longer period of time or, for example, file a divisional application.

For a design application, the advantage of the request for a delayed examination is that the publication of the design, which is i.a. linked to the payment of the registration fee, can be postponed for a longer period.

We are happy to advise and support you concerning the examination of the facts and the possibilities of implementation with regard to your IP rights in China.

CNIPA was established in August 2018; from the former Chinese Patent and Trademark Office (SIPO - Intellectual Property Office of China). Since then, CNIPA has been supervised by the newly established State Administration for market surveillance and market administration. Besides patents, utility models and designs, CNIPA now also deals with trademarks and geographical indications.

11. December 2019 – The Unitary Patent Court: The German decision is expected at the beginning of 2020

For some years now, the establishment of a European Unitary Patent and a Unitary Patent Court within the EU member states has been discussed. In order for it to come into effect, the agreement must be ratified by all EU member states.

According to professional sources, the Federal Constitutional Court is seeking to reach a decision at the beginning of 2020 on the constitutional complaint that has been pending since 2017 against the ratification of the Convention for an Unitary European Patent Court in Germany.

However, a decision by the Federal Constitutional Court may be delayed as the ministry of justice announced this summer that the government will not ratify the agreement until the impact and consequences of the upcoming Brexit are clear.

The UK's date of withdrawal from the European Union has been postponed several times since the EU referendum in 2016; most recently to January, 31st 2020.

It is still uncertain whether the court will decide in time for the United Kingdom to participate in the new patent court. Only those EU member states can be part of the Unitary Patent Court (UPC) which have ratified the agreement when the UPC enters into force.

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.
