A Key Point on Obviousess from "The Love Slides"
Prior art is not limited to the four corners of the documentary prior art being applied.
• Prior art includes both the specialized understanding of one of
ordinary skill in the art, and the common understanding of the layman.
• It includes "background knowledge possessed by a person having ordinary skill in
the art. . . . [A] court can take account of the inferences and creative steps
that a person of ordinary skill in the art would employ." KSRat 1396.
Examiners may rely on, for example, official notice, common sense, and design choice.
