Nathan Clifford, McLean v. Fleming — Opinion of the Court
“ Words or devices, or even a name in certain cases, may be adopted as trade-marks which are not the original invention of the party who appropriates the same to that use; and courts of equity will protect the proprietor against any fraudulent use or imitation of the device by other dealers or manufacturers. Property in the use of a trade-mark, however, bears very little analogy to that which exists in copyrights or in patents for new inventions or discoveries, as they are not required to be new, and may not involve the least invention or skill in their discovery or application. ”
