Randal C. Picker of the University of Chicago Law School has self-archived "The Google Book Search Settlement: A New Orphan-Works Monopoly?" in SSRN.
Here's an excerpt:
The settlement agreement is exceeding complex but I have focused on three issues that raise antitrust and competition policy concerns. First, the agreement calls for Google to act as agent for rights holders in setting the price of online access to consumers. Google is tasked with developing a pricing algorithm that will maximize revenues for each of those works. Direct competition among rights holders would push prices towards some measure of costs and would not be designed to maximize revenues. As I think that level of direct coordination of prices is unlikely to mimic what would result in competition, I have real doubts about whether the consumer access pricing provision would survive a challenge under Section 1 of the Sherman Act.
Second, and much more centrally to the settlement agreement, the opt out class action will make it possible for Google to include orphan works in its book search service. Orphan works are works as to which the rightsholder can't be identified or found. That means that a firm like Google can't contract with an orphan holder directly to include his or her work in the service and that would result in large numbers of missing works. The opt out mechanism—which shifts the default from copyright's usual out to the class action's in—brings these works into the settlement. . . .
Third, there is a risk that approval by the court of the settlement could cause antitrust immunities to attach to the arrangements created by the settlement agreement. As it is highly unlikely that the fairness hearing will undertake a meaningful antitrust analysis of those arrangements, if the district court approves the settlement, the court should include a clause—call this a no Noerr clause—in the order approving the settlement providing that no antitrust immunities attach from the court's approval.
