G.ho.st says Microsoft stole "No Walls" slogan This much is provable: G.ho.st, a hosted service that dubs itself the Global Hosted Operating SysTem, uses a slogan, "No Walls." Microsoft's new Seinfeld-powered Windows campaign pushes several slogans, including "Imagine No Walls." Sleep-deprived superreporter Kara Swisher tells us the G.ho.st gang claims trademark infringement on a pending trademark for "No walls." Our attempts to pull G.ho.st's trademark entry from the United States Patent and Trademark Office's searchable database returned no matches to G.ho.st's claim. Ball in your court, G.ho.st.ers — post your USPTO documentation in the comments, or it didn't happen.
