But if I've dissolved my American LLC and sold/transferred all its assets to my new LLC (or LLC equivalent) in $COUNTRY, what can they really do? They can't sue my old LLC, it's nonexistent. They can't sue me, I'm not liable for the activities of my American LLC. They could sue my new LLC, but they'd have to file in $COUNTRY, where the patent (or whatever) laws are more favorable to me. I suppose they could get an injunction in the U.S. to prevent my new LLC from selling to customers here, but with a webapp that I just sell subscriptions to, how could they enforce that? I'm sure that I'm missing something here, but I don't know what.
