As others have said, it is really not a new rule. Maybe it would be better off as part of the manual that gets released before kick off. But it means that if you design a gear box, publish enough information that a reasonable person could make it, you can use the same plans. You also cannot use critical information you withhold. Something that was a little unclear in previous years rules blue box descriptions.

Like a good many rules in First, it is relying on the GP on teams to fully follow the rule.
