 A prior art source may thus still anticipate if an apparently missing element of the claim is inherent in that prior art source.Procedurally, to rely on the doctrine of inherency, one must provide a basis in fact and/or technical reasoning supporting a determination that an allegedly inherent characteristic necessarily would be present if the teachings of the prior art were followed, even if the inherent feature would not have been recognized.The fact that a certain result or characteristic may occur or be present in the prior art is not alone sufficient to establish inherency of that result or characteristic.
