Admittedly, when countries have trade agreements with one another, laws get rewritten to align countries with one another on things like IP. So foreign laws have a way it spilling over when new agreements are created. It usually goes both ways, to some extent, but the US can throw their weight around more than most.

In the agreement between Canada and the EU, for example, there are international mobility clauses in there for professionals (engineers, etc.) allowing them to bid on work in each other’s jurisdictions. This of course required some work because laws on both sides needed adjusting. So laws governing the behaviour of engineers align slightly more now than before. Doesn’t mean we’re subject to EU law in Canada, but the example is illustrative.
