S&B is pursuing a trademark infringement lawsuit against entertainment company Roc Nation, which is essentially a partnership between musical artist Jay-Z and ticket producer Live Nation, over its use of the name "Hugo" for one of its musical artists. S&B represents a musical artist who has been using that name for years and who possesses a trademark that has been registered with the United States Patent and Trademark Office. S&B's suit also names Live Nation and the musical artist whose name is Chulachak Chakrabongse, who has achieved recognition for recordings such as "Bread & Butter" and his cover of "99 Problems". "This is a case about consumer confusion", handling attorney William Buus said, "and whether it is right – legally and morally – for one to take another's business goodwill by using a name that the other invested time, money and effort in building. Quite simply, it's not."
