whole or in part.
agreement might have been to require a party to buy the tied product from the maker of the tying product simply to
would the maker have done if a party had bought the competition’s product? The purpose might have related more
practically to the maker’s tying product, however—to lengthen its life, for example—but other means to achieve this
purpose might then be weighed to assess the legitimacy of the tying agreement.
The Internet Corporation for Assigned Names and Numbers (ICANN) is a nonprofit entity that organizes
Internet domain names. It is governed by a board of directors elected by various groups with commercial
interests in the Internet. One of ICANN’s functions is to authorize an entity to serve as a registrar for certain
“Top Level Domains” (TLDs). ICANN and VeriSign entered into an agreement that authorized VeriSign to
provide registry services in accordance with ICANN’s specifications. VeriSign complained that ICANN was
restricting the services that it could make available as a registrar and was blocking new services, imposing
unnecessary conditions on those services, and setting the prices at which the services were offered. VeriSign
claimed that ICANN’s control of the registry services for domain names violated Section 1 of the Sherman
Act. Ask your students to answer the following questions, using the information presented in the chapter.
1. Should ICANN’s actions be judged under the rule of reason or deemed per se violations of Section
1 of the Sherman Act? Because ICANN is at a higher level of the distribution process than Verisign, it is
imposing a vertical restraint. Since the vertical restraint that Verisign complains of involves restrictions on
services that Verisign can offer (customer restrictions) and the setting of prices at which Verisign can sell its
services (resale price maintenance agreement), ICANN’s action should be judged under the rule of reason.
2. Should ICANN’s actions be viewed as a horizontal or a vertical restraint of trade? Why? Vertical.
Because ICANN and Verisign are firms at different levels in the distribution of top-level domain names, the
actions that Verisign complains of are a vertical restraint. ICANN, which is Verisign’s superior, is allegedly
placing restrictions on what services Verisign can offer, and how much it can charge for its services. This
amounts to a vertical restraint.
3. Does it matter that ICANN’s directors are chosen by groups with a commercial interest in the
Internet? Explain. If ICANN’s leadership was chosen by those with a commercial interest in the Internet, the
directors might represent commercial interests with significant market power and restrain trade in violation of
the Sherman Act.
4. If the dispute is judged under the rule of reason, what might be ICANN’s defense for having a
standardized set of registry services that must be used? ICANN’s best defense is to assert that a
standardized set of registry services is efficient and has the effect of promoting competition rather than
suppressing it. Under the rule of reason, as long as an agreement is merely regulatory and does not
unreasonably restrain trade, it should not be considered illegal.
