Thelen representatives informed a New York bankruptcy court judge this week that the defunct law firm has recently settled unfinished business claims with four more law firms, bringing to 20 the number of firms that have agreed to make payments to the Thelen estate so far this year.

Some of those settlements are tied to a spate of lawsuits filed by Thelen’s Chapter 7 bankruptcy trustee, Fox Rothschild partner Yann Geron, last September against former firm clients, ex-Thelen partners and 16 law firms. When he filed the suits — with time running out on his ability to launch such litigation — Geron said there were other law firms he was pursuing but had not yet sued because settlement negotiations were under way.
