I heard about this on Russell Beattie’s post
I posted my comment on moco news which says ..
I read about this issue on Russell Beattie’s post and agree you have a case here. The trademark filing gives it away. I also read both (moco and fiercewireless) and I agree with you that moco is not a generic name. The trends are ominoious ..
think fiercefuturetext, fiercebeattie , fiercemobhappy, fierce160characters etc etc ..
I shall blog about this as well
you can post your comment in support of the moco guys at HERE
