Hagens Berman has moved to intervene in at least five “copycat” lawsuits in federal court in New York. The firm said it hopes to consolidate all of the litigation in the Northern District of California, where it is pursuing a price-fixing case against electronic book publishers and retailers.

In an Aug. 24 motion, filed in all five cases, Jason Zweig, of counsel in the Seattle firm’s New York office, argued that their core allegations were identical to those brought by his firm.
