but I question their decision in the face (pun intended ) of them not attacking some of the other’s mentioned in the same suit.
I believe one of Facebook’s people commented on that in the Techcrunch link above. Not that anyone has to agree with or believe them, but…what they said is their position.
While not a lawyer, I’ve since learned that trademark infringement essentially boils down to what’s called likelihood of confusion; that the general public may confuse someone’s service with a trademark.
Of course, that’s what Facebook aims to prove in their complaint against Teachbook. Unfortunately they seem prepared to do so, notwithstanding how much financial muscle they can afford.
Then again, Teachbook is defended by Greenburg Taurig. Look ’em up, and they’re not exactly cheap either.
At the end of this, Facebook will probably use a polling firm to determine if the general public will likely confuse Teachbook with Facebook or not. Time will tell.
