Eric Landau, a prominent Irvine, California-based securities litigator whose alleged sexist behavior was highlighted in $200 million proposed gender bias class action filed against Jones Day earlier this month, has departed the firm.

The exact timing of his exit is uncertain. An email sent to his firm address prompted a return message stating that he is “no longer with Jones Day.” Data from ALM’s Legal Compass indicates the firm took down his bio and a related page Jan. 16, well before the complaint was filed, but it’s unclear whether he left the firm at that time or later.
