definiens: means any compound that is an isomer, homolog, analog or prodrug of the GenuProCompound and that is made, identified or characterized at any time by Licensee, [COMPANY], [COMPANY] or Lilly ( to the extent to whichGenuPro or [COMPANY] has rights to such compounds made, identified or characterized by Lilly ) . The term includescompounds of identical elemental composition ( empirical formulae ) and specifically encompassing chain, geometrical, sterochemical, keto - enol, optical and position isomerism . The term includes carbon compounds, conforming tothe same general formula and in which each member differs from another by a constant linear increment of the atomic groups – CH2- or – CH2 - CH2- .
