Portrait of Harlan F. Stone Harlan F. Stone Ethyl Gasoline Corporation v. United States…

There is no authentic instance of injury resulting from the handling of leadtreated gasoline after its manufacture attributable to its lead content. Extensive expert study, carried on under direction of appellant over a period of years, detailed in the record, resulted in a report that the risk arising from the absorption of lead through the skin in the handling of the lead-treated fuel is so small as to be negligible, and that the use of the fuel made in conformity to the refiners' licenses has not caused or produced any dangers or hazards to health.

The extent to which appellant's dominion over the jobbers' business goes beyond its patent monopoly, is emphasized by the circumstances here present that the prices and market practices sought to be established are not those prescribed by appellant-patentee, but by the refiners. Appellant neither owns nor sells the patented fuel nor derives any profit through royalties or otherwise from its sale. It has chosen to exploit its patents by manufacturing the fluid covered by them and by selling that fluid to refiners for use in the manufacture of motor fuel.

The octane rating of motor fuel increases with the amount of the patented fluid added to the gasoline which, in any case, is small. Appellant's licenses to refiners authorize the manufacture of gasoline of high octane rating, 68 or more, of two classes, 'regular', in which there is one part of tetraethyl lead to 4200 parts of gasoline, and 'ethyl gasoline', in which there is one part of tetraethyl lead to 1700 parts of gasoline.↑ The name of the Ethyl Corporation and its trademark or trade names 'Ethyl' and 'Q' may not be used in connection with the advertising and sale of regular gasoline.
