The lawsuit was filed yesterday (August 11, 2015) in a Federal District Court located in Massachusetts.
From the Complaint:
Defendants [listed in complaint below] are in the business of textbook arbitrage. They purchase textbooks at the lowest possible prices at which they can find them, and then sell them at a profit to distributors and consumers. In order to maximize their profit, Defendants often buy books from unknown sources at below market prices. Frequently, these sources are overseas sources or unkn own Internet sellers.
In the course of their book arbitrage, Defendants purchase counterfeit books, which they then sell to others as legitimate textbooks. From time to time, Defendants have been put on notice that books they are selling are counterfeit.
Even after they have been told that certain books they have purchased are counterfeit, they have sold them to consumers and distributors as though they are legitimate.
