PFOA and PFOS are part of the family of manmade compounds called perfluoroalkyl acids, which humans are exposed to through everything from dust to food packaging to microwave popcorn and non-stick pots and pans.
-
Perfluoro-octanoic acid belongs to the family of stable synthetic materials called perfluoroalkyl acids.
-
Humans are exposed to the man-made compounds known as perfluoroalkyl acids-including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) - through drinking water, dust, food packaging, breast milk, cord blood, microwave popcorn, air and occupational exposure.

While Yamamoto's genus of surfactants is arguably broad, it nevertheless consists of only a finite number of known perfluoroalkyl surfactants that predictably solve the dispersion problem of the charge transport agent into the binder resin.

Because that person having ordinary skill in the art would have "anticipated success" in trying GF-300 perfluoroalkyl surfactant in view of Yamamoto's teachings, the subject matter of appealed claim 1 would have been prima facie obvious over Yamamoto alone.

Perfluorooctanoic acid (PFOA), also known as “C8”, is a synthetic chemical and one of the perfluoroalkyl acids used to make fluoropolymers during the manufacture of a wide variety of products.

Following the discovery that perfluoroalkyl substances are persistent in the environment, researchers began to focus on measuring PFOA in wildlife and in surface water.

It would have been within the "technical grasp" of that person having ordinary skill in the art to understand that this known surfactant, which was readily available in commerce, has the perfluoroalkyl group as required by Yamamoto.
