He Says He Owns the Word 'Stealth' (Actually, He Claims 'Chutzpah,' Too):
Over the last few years, Leo Stoller has written dozens of letters to companies and organizations and individuals stating that he owns the trademark to "stealth." He has threatened to sue people who have used the word without his permission. In some cases, he has offered to drop objections in exchange for thousands of dollars. And in a few of those instances, people or companies have paid up.
Mr. Stoller owns and runs a company called Rentamark.com, which offers, among other things, advice on sending cease-and-desist letters and Mr. Stoller's services as an expert witness in trademark trials. Through Rentamark, Mr. Stoller offers licensing agreements for other words he says he owns and controls, such as bootlegger, hoax and chutzpah.
