Someone on another board was asking about this so I thought I would ask it here, since there are so many good minds on this board.
Checking wikipedia, I see that Martin Goodman's grandson, Jason Goodman, started up Atlas again in 2010. And at that time they were doing more of Grim Ghost, Phoenix and Wulf the Barbarian. I don't know what came of that.
But since Atlas/Seaboard granted ownership rights to the creators working for them (which is why so much talent came their way) do those creators still hold the rights? Or did those rights lapse?
Did Martin Goodman retain some ownership rights, as well? If his grandson could restart the company, you'd think the family must retain some copyright.
I wonder if the whole company is fractured under different copyright holders, if some is in the public domain or if it's all held by one owner.
