Samuel Freeman Miller,
Trade-Mark Cases (100 U.S. 82)…
“ The trade-mark may be, and generally is, the adoption of something already in existence as the distinctive symbol of the party using it. At common law the exclusive right to it grows out of its use, and not its mere adoption. By the act of Congress this exclusive right attaches upon registration. But in neither case does it depend upon novelty, invention, discovery, or any work of the brain. It requires no fancy or imagination, no genius, no laborious thought. It is simply founded on priority of appropriation. We look in vain in the statute for any other qualification or condition. ”
