they'd be dumb not to settle
There's no reason for them to settle. The current dynamic is that if they do nothing, they get the domain name. If the case has not been served on them, then it's Rob who has to go to court to argue to keep the case alive.
On the other side, if the point of this litigation was to do things like:
- Challenge WIPO's right to exist in the court of public opinion -- this is in progress and I appreciate the support to keep this thread prominent.
or
then reaching a settlement with the complainant in this UDRP case doesn't get anywhere near those things.
You litigate for two reasons: (1) to prove a point and make some law, or (2) to remedy a problem which the law is capable of addressing.
If you are in the business of making points, then you don't settle. For example, if the inter-racial couple who sued the State of Virginia in Loving v. Virginia had settled with the State of Virginia on the basis of "Okay, we'll let you two get married", that would have solved their immediate problem, but would do nothing for anyone else.
But there is no settlement here which is going to affect "WIPO's right to exist". That's kind of a tall order anyway since WIPO is an organization that was created by a treaty among quite a large number of countries, including the US, to administer certain tasks under that treaty. In the larger scheme of things, the UDRP is a teeny-tiny part of what WIPO does, and is a small money-losing part of their otherwise considerable budget from the Patent Cooperation Treaty chunk of their operations.
As for the second goal above, we are approaching seven months into 2020, and I don't see much evidence of "the industry" fighting back against WIPO, nor is there any imminent threat to "WIPO's right to exist". Part of the reason the UDRP exists was to get registrars out of the business of adjudicating trademark claims, and to offload potentially liability for those sorts of decisions.
So, in any event, settling with the other side certainly doesn't advance any stated goal of the litigation. If one were advising a well-funded company on the best approach to dealing with a pro se litigator, then the best advice, absent service having been made, is to let that pro se litigator flounder about and see if the court dismisses the case on its own.
