(Thank you sir.)
Unless they patent something ridiculously useful, scientists are usually on a production line or working out of science kennels, so either dad had money or married money... So if Mom was the money who married a scientist, I can only her sextalk with coming of age Janet: "Find a scientist, the bigger the brain the better, trust me, later it really counts between the sheets."
But if Hank Pym invented Pym Particles (The Man in the Ant Hill, seemed to be the work off an independent?) then surely Van Dyne Industries owns Pym particles... And probably Ultron too.
Of course, he could have got them back in the divorce?
(Did Hank and Janet Get divorced, or did some Skrull and Janet get a Divorce?)
