In the late 1980s, respondent
SEB, S.A., a French maker of home appliances, invented an innovative
deep fryer, the external surfaces of which remain cool-to-the-touch during operation. The "cool-touch" fryer consisted of a framing that suspends the metal frying pot within the plastic housing, leaving an insulating air space between the heated pot and the exterior. SEB obtained U.S. Patent No. 4,995,312 for this design in 1991 and began manufacturing and selling it under the
T-Fal brand. With no similar products in the American market, the fryer became a commercial success. In 1997,
Sunbeam Products asked Pentalpha Enterprises, Ltd., a Hong Kong maker of home appliances and wholly owned subsidiary of Global-Tech Appliances, Inc., to design a deep fryer meeting certain specifications that could be sold under the Sunbeam label. To fulfill the request, Pentalpha purchased an SEB fryer in Hong Kong which lacked the U.S. patent notices and copied all but its cosmetic features. Pentalpha then retained an attorney to conduct a right-to-use study for the United States, but neglected to inform the attorney that the design was copied from an SEB fryer. Failing to discover SEB's patent, the attorney issued an opinion letter in August, 1997, stating that Pentalpha's product did not infringe upon any U.S. patents that he had found. That same month, Pentalpha began manufacturing and selling its fryer to Sunbeam, which sold them in the United States. Second, SEB claimed that Pentalpha had induced Sunbeam, Fingerhut, and Montgomery Ward to infringe upon the patent, contravening §271(b). Pentalpha then filed a petition for a
writ of certiorari to the Federal Circuit with the Supreme Court on June 23, 2010. == Opinion of the Court ==
