IIRC Trade Enforcement Regulation allows, among other options, for ignoring other country’s patents and trademarks until someone else says it’s time to stop. Correct me if I’m wrong.

Edit: Seems like I misremembered, because I can’t find it mentioned in the regulation 654/2014, my bad

Edit 2: Okay, I think I’ve found it - 654/2014 was amended by 2021/167, and as far as I understand legalese THAT one allows for suspension of intellectual property rights. I’ll wait with un-stroking the original paragraph until someone more knowledgeable confirms (or denies) my understanding
