He is possessed enough to trademark his name, but only for recordings and live music, so it rules out clothing. What was not mentioned in the article is that he didn't write Take It Easy, Jackson Browne did. His band recorded the song, but has no claim on ownership of the song, only their recording. I'm sure he doesn't have that either, it's in the hands of the record label. To misquote Styx, I think Henley has Too Much Time On His Hands.
