"No Walls" Trademark Dispute (Maybe Microsoft Should Bring Back Seinfeld)

An unusual Israeli-Palestinian joint venture start-up, which makes a cloud-based Web operating system letting users access their desktops from any computer with an Internet connection, is alleging a trademark violation by Microsoft in its new $300 million advertising campaign. G.ho.st, which stands for “Global Hosted Operating System,” claims it has a pending trademark registration for the tagline “no walls.” Microsoft disputes G.ho.st’s contention.
