In the Famous DuPont Cellophane Case, the Supreme Court Ruled

In the famous DuPont cellophane case, the Supreme Court ruled that even though DuPont had a 75 percent market share in cellophane, it did not have monopoly power in cellophane, because:

A) other functionally equivalent products were available in the market.
B) DuPont had not acquired its market power through improper means.
C) cellophane was not a significant product in Interstate commerce.
D) inference of monopoly power requires market share in excess of 80 percent.
