[Fedora-legal-list] IDEA patent expiration?

[Orcan Ogetbil]

Hi all,

We explicitly exclude the "International Data Encryption Algorithm"
(IDEA) in a few Fedora packages (bouncycastle, opengpg, ?) due to its
patent issues. Recently it occurred to me that this patent  [1] may
actually have been expired by now. There is some debate in the
wikipedia's discussion page about this topic [2]. From what I
understand, the general perception is that the US patent expired in
May 2011.

Could you please check this?
When is it possible to have the IDEA in Fedora?

Thanks,
Orcan
