Did no one pick up the patent? Or look into it (AFAIK, patents aren't top-secret)?
I'm quite sure patents are public. So if those involved knew they were "suppressed", why not tell more people about it, or snatch the technology once it's free?

Precisely - patents are public; they can't be used to suppress something or keep it secret. Precisely the opposite, in fact.
