Want to know something fun about US parents??
Patents don't really protect new inventions. They give people a right to sue for financial damages and there is no criminal force of law (this is a generalization and I am not a lawyer). So courts don't really go "hey, stop using invention ABC, someone else has a patent on it." They just say "hey, that other guy invented it first, give him some money."
Patents (not other forms of IP) are made to be wildly public so people can invent things on top of previous inventions.
Does it always work like that? No. But it's one facet of US federal law that I find interesting, and a little bit hopeful.
