Seems like to me, that they are shafting you on this.
My thoughts are this, the places that have the most control over these matters, have not and do not even try to prevent this stuff.
First you got the TM holder, they have time to make claim before you got it on any real TM they hold.
Then you got godaddy or any other place selling domains, that are TM names and making money on them. The last time I looked at the law, you can't sell TM item or you was in trouble for it. But yet they do it all the time, and think nothing of just taking it back to put on hold.
You also got dotmobi that could make a list of domains, that are of known TM problems. And not sell any of them in the first place, at all 3 steps they done nothing to prevent this from happing. And place all of it on the buyer of the domains, that in most cases do not have the means to know or prevent this stuff.
I read the dotmobi rules, anyone can open a case any time they want on them. Meaning it does not matter they did not try to get it, why should they when they can do it any time they want. So this sunrise is a alot of crap, it does nothing for anyone but dotmobi that is clear.
First they got lots of money, and can push people around that don't have it. Godaddy only cares about the money they can make, they got $29 so they are not worrying about it any.
One thing I have thought of, is you can tell them that if they lose, their TM will lose alot of it's value. How can they then defend it from other people, it's a good way to make them worry a little bit.
You could bring up about the sunrise time, and them not trying to get the domain then. And that in most places, running a legal ad about a name for a time and if no one has claim on it it's yours. I do believe this is the case with TM as well, and try to say that the sunrise should serve for the same thing.
You need to get or make a logo and other stuff for the domain name, to show you was indeed going to use the domain name. Make a site on your desktop, you can say that you had it done and was going to upload it, just before godaddy put ahold on it.
That is what I would do, it should be able to show fair usage of the domain. Will it work, I don't know but it will indeed give them some thing to think about I think. You remember microsoft, paying some thing like 20 million for lindows. That is because if microsoft lost the case, they will not be able to protect the TM very good after that. So they paid them 20 million bucks for it, so it does indeed make these big places worry over it.
