    In United States patent law, the doctrine of inherency holds that, under certain circumstances, prior art may be relied upon not only for what it expressly teaches, but also for what is inherent therein, i.e., what necessarily flows from the express teachings.

Greenwood, 52 U.S. (11 How.) 248 (1851), was a United States Supreme Court decision credited with introducing into United States patent law the concept of non-obviousness as a patentability requirement, [1] as well as stating the applicable legal standard for determining its presence or absence in a claimed invention.
