The mark consists of the phrase "hemex QUANTUM" in which the "h" is the symbol for Planck's constant, and the bottom right tail of the "h" connects to the top left of the "x" creating an arch over the "eme" portion of "hemex". The "QUANTUM" portion immediately follows "hemex" and is in a smaller sized font which is all capitalized and italicized.
Color is not claimed as a feature of the mark.
