Correct. Sometimes, Ex, to show “how” something is formulaically derived, one can provide the formula, or, they can do something else.
The judge assumes the formula is, for now, 100% in the sole possession of defendants, but he still wants to know how plaintiffs would know what they are are claiming, without necessarily providing the formula.
Of course, plaintiffs stated they are “fully prepared” to provide what the court is asking for plus anything else. So, you know….
(Note:The Judge’s assumption and plaintiff’s readiness provides a potential opportunity for early settlement imho, which is what I opined a number of days ago.)
