might be hard for him to do. Entering two markets having unrelated production
characteristics might both entail delay and increase the risk and hence cost of
the new entrant.
[3] Headnote Citing References Tying agreements can also be a method of price
from the low price of the machine. See Eastman Kodak Co. v. Image Technical
Services, Inc., 504 U.S. 451, 475-76, 112 S.Ct. 2072, 119 L.Ed.2d 265 (1992);
Mozart Co. v. Mercedes-Benz of North America, Inc., 833 F.2d 1342, 1345 n. 3
(9th Cir.1987); Hirsh v. Martindale-Hubbell, Inc., 674 F.2d 1343, 1348-49 (9th
Cir.1982). However, price discrimination does not violate the Sherman Act unless
agreements illegal provided only that, as the language of section 3 of the Clayton
Act seemed to require, the tying arrangement embraced a nontrivial amount of
interstate commerce. E.g., Northern Pacific Ry. v. United States, 356 U.S. 1, 5-7,
78 S.Ct. 514, 2 L.Ed.2d 545 (1958); International Salt Co. v. United States, 332
U.S. 392, 396, 68 S.Ct. 12, 92 L.Ed. 20 (1947). In the 1970s, however, the Court
2549, 53 L.Ed.2d 568 (1977) (territorial restrictions in distribution); cf. Illinois Tool
Works, Inc. v. Independent Ink, Inc., 547 U.S. 28, 126 S.Ct. 1281, 164 L.Ed.2d
26 (2006). The Court has not discarded the tying rule, and we have no authority
to do so. But it has *594 modified the rule by requiring proof that the seller has
“market power” in the market for the tying product. Illinois Tool Works, Inc. v.
109-10, 104 S.Ct. 2948, 82 L.Ed.2d 70 (1984); U.S. Healthcare, Inc. v.
