Alternatively, Harmony Gold could put in its settlement that they won't go after anyone for those 41 character designs anymore, at which point...well, their settlement would abrogate their complaint against CGL. But that's pie-in-the-sky hopefulness.
Which HG would never do and I don't see PGI being able to force it in a legal way.
In all honesty, why wouldn't that be in the settlement? I imagine that would at least be PGI's starting position and something that can be negotiated away. However, it is probably more viable that we think, because look at what can happen if this goes to trial and HG loses:
1. HG loses the ability to go after anyone for the 41 anyway, but also can see hefty legal fines and suffer a humiliating defeat that very publicly damages them to other companies... companies such as Sony Pictures. Legally, they know this is a possibility or they wouldn't be in settlement talks. It would literally take anyone with the funds to go to court and win this.
2. Due to their recent arbitration with Tatsunoko, they potentially lose all access to Macross as an exploitable source material in 2021 anyway. How actually soured that relationship is, we don't know, but it is possible. So then what would be the point of wringing out a bit of money from the dried rag that is CGL only to lose the license for something you are fighting for in under three years anyway?
However, if it is included in the settlement, maybe no one pays anyone anything and everyone just goes about their business. PGI's stance based on the emails that were shared in the case and what has been said has been, "We want to work this out for everyone." Even Brent and Loren at last year's GenCon said the same thing. HG doesn't pay any big fines and maybe they get a case of Coca Cola or whatever. They don't suffer monetary loses or lose major face to other potential business partners.
I understand that is an unlikely scenario, but it would be a happy-ish way out for everyone.
