I will say that even with your objection Bathesda will NOT let the court solve this for them unless they are guarenteed to win.
With a out of court settlement they can keep people away from "Scrolls". With the courts going in favor of the game they create precident.
Sweden is a civil law system country unbounded by prec
edents.
I'll describe about how IP laws operate to my knowledge below. (which my country is using civil law system as well. It's a bit different with the common law system in US and UK familiar with.)
IP (Intellectual Property) opposition and infringement are different. The process of opposed a registered trademark (which is required to consist of infringement within civilian law system) is separated from a civil lawsuit. (physical law and lawsuit law are separated as well - i.e substantive law separated from procedural law). When an opposition in published trademark is filed (administrative lawsuit, and it needs to be done within 3 months from published), it goes to a proceeding with a period of "cooling-off" time before the formal ruling proceeds. Up till this stage, none of the party is "in court/in trial" yet. But technically it's already in the process of lawsuit procedures. This period of "settlement" should be at minimum 2 months in Euro CTMA. (Can be extended up to 2 years) counting from the day of notification of admissibility. (7/30, so the real proceeding should begin at 9/30 as the earliest possible date). And if and only if that this ruling is over than the appeal by either party can "go into court" ( appeal to higher court).
Now since "civil lawsuit" it's separated. The "civil court" (which is just a court in general with civil lawsuit cases. An infringement can also be applied to criminal lawsuit as well, but I think few trademark cases going for it) can not rule whether a trademark is valid or not (It's up to the professionals in IP court), their function is to determine if the infringement caused for damages and issuing injunctions to stop infringements. It can enforce the outcome when private settlement can not. This is not required and from what I am gathering, I guess this is not really entering a civil lawsuit yet. (I can't find any district court case that matches it, but I don't read Sweden, so I've likely missed it if it did. Thus I'd like to know if someone in Sweden can look it up). But traditionally the preparation of both should happen simultaneously, since you don't want to get an approval of your opposition, but not able to enforce them. (And for getting the damages money quickly) And I don't know what Notch said about Zenimax paid the fee for the court was meant for the previous mentioned IP court proceedings (indeed it should), or also for the "civil court" lawsuit as well [1].
Law and lawsuit processes have evolved into a wildly covered and professional system. And it's certainly not just a simple decision of whether letting the court to solve it or not question anymore. I doubt the man in change of Zenimax who is a lawyer will not know what to do about it. But their decisions may be indeed far off from ideal. People do make mistakes whether it's you, me, lawyers, CEOs, judges, or Notch.
[1] P.S. I can't be sure since both record of fee submissions should not be public. I guess a civil lawsuit preparation probably is taking place, but who knows. Perhaps Bethesda will not want to enforce it, and just want to clear the trademark dispute only, hopefully Notch will comply in the end. However It will be quite foolish to not get prepared if you want to defend your IP rights.
And IP is like property, they can be sold, lent, transfer, etc. If Notch do get the registered "SCROLLS" trademark ruling in the end as he want, there is nothing Bethesda can do if Notch sold it (Selling the IP right, is NOT selling the game, Notch can still be the developer. It's separated). And the agreement between Notch and Zenimax doesn't apply to the new owner. And who knows the next owner will be like Notch. (It may be a big gaming company as well, then it will be a major trouble for Bethesda).
