Disclosure: I'm not a lawyer. This is based om my experience being sued by a previous employer. They was in the EU, laws may be different in other parts of the world. If your (former) employer wants to sue you for IP theft, they must prove the damage you did to them, which is really, really hard. They can't sue you over stuff you learned while you worked somewhere. Your contract may say so, but it wont hold up in court, because you wouldn't be able to do your work without that experience.
