Dreier LLP is demanding its share of the millions of dollars in fees earned from litigation that its former patent lawyers continued working on after the firm’s collapse, the Wall Street Journal reported on Saturday. Bankruptcy trustee Sheila M. Gowan, who is running Dreier’s liquidation, on Wednesday sued three former Dreier partners to recover the profits from the unfinished business the partners took with them when they left the firm. The firm dissolved and went into bankruptcy in December 2008, days after founder Marc Dreier was arrested for defrauding hedge funds and other investors out of more than $400 million.
