Heading: Validity--Permatire

Text: 6 Synair points to several sales of Arnco's product Permatire where the water present in the material may have exceeded 0.1%, arguing that these sales act as an anticipation under 35 USC 102(b). As discussed in subsection A, supra, we agree with the District Court that the claims require the intentional addition of at least 0.1% water. Thus, any isolated sales of Permatire containing in excess of 0.1% water would not constitute anticipation, since the water present was not, as required by the claims, intentionally added. 7 The District Court also did not err in failing to take the Permatire sales into account in determining obviousness. While isolated batches of Permatire material may have had in excess of 0.1% water, that water amount was neither intentional nor desirable, and so could not provide the motivation necessary to add water to other prior art tire filling compositions such as that disclosed in the prior art Gomberg patent.
