Does Size Matter? Nanoscale Particle Size As An Indicator Of Inherency In Nanopharmaceutical Patent Validity, Kirsten Fehlan

Georgia State University Law Review

Scientific and technological advances in nanopharmaceuticals bring the doctrine of inherent obviousness to a head. On the one hand, nanotechnology promises to offer novel ways to target and treat traditionally incurable diseases by operating at a scale that is comparable to the scales that most biological systems use. On the other hand, nanotechnology inventions that result in improved pharmacokinetic properties are susceptible to validity challenges based on inherent obviousness.

Inherency and obviousness are two independently recognized and well-understood principles in United States patent law. Inherency refers to a claimed limitation or feature that is either necessarily present in, or the …
