Earlier quoted context omitted.
Russia is party to several international treaties that allow it to be sued outside of Russian courts if it doesn't uphold intellectual property law, and if those suits do not go Russia's way, then it is now possible that Russian assets can be seized as compensation. Or, to oversimplify it, if Russia decides that anyone can use McDonald's trademark, then maybe Gazprom's pipelines won't be Russian anymore.
Hasn't the US already been seizing stuff somewhat randomly? I don't think there is a case that Russian yachts are contributing to the war effort, but there seems to be a push on to make off with them.
“We are already working with our international partners to freeze and seize properties belonging to sanctioned Russian oligarchs worldwide,” said Attorney General Garland. “We will continue to work together to take all appropriate actions against those whose criminal acts enable the Russian government to continue its unjust war against Ukraine.”
