In general, a compound is non-obvious over the structurally related prior art if the compound exhibits unexpected results. However, placing primary emphasis on a compound's unexpected properties is out of step with the realities of drug development. For example, during drug development, chemists will modify a compound's structure until they produce a compound that exhibits optimal pharmakinetic properties. This …
