I hope that Warners ultimately is forced to beg the heirs for crumbs.

The idea was that the studio and publisher hired attorney Daniel Petrocelli to come up with a new strategy to prevent the studio from possibly losing a portion of the copyright to Superman in 2013 as a court has previously ruled. So Warner Bros new outside counsel obliged by filing a lawsuit last May obviously to put Toberoff in a position where he might have to resign as the Siegel and Shuster attorney. It was a hardball tactic by Petrocelli and the studio's general counsel John Rogovin (hiding behind DC Comics), especially because it hinges on those documents stolen from Toberoff's office by a Toberoff employee.
Warner Bros claims the documents mysteriously "arrived" on its doorstep and that the employee was a lawyer in Toberoff's firm and a "whistleblower". Toberoff has indicated that something much more nefarious may have happened and accused DC/WB of "unethical thug tactics".
