This seems to be referencing Regulation (EU) 654/2014, an EU law which allows the EU to unilaterally enact countermeasures against countries that break the WTO's rules.
The countermeasures listed in article 5 are:
- Imposing tarriffs and customs duties
- Trade restrictions/quotas
- Cancelling contracts between the EU and the target country
- Cancelling the target country's intellectual property rights (e.g. patents/copyrights)
- Banning public procurement from the target country
- Implementing price penalties for public procurement from the target country
The law was amended in Regulation (EU) 2021/167 in response to the Trump (and now Biden) administrations blocking the appointment of judges to the WTO and using a loophole to kill the WTO's enforcement mechanism.

The fact that the EU can just suspend American patents and copyrights is pretty insane. Could be some huge benefits for European companies and movie pirates.
