[Fedora-legal-list] IDEA patent expiration?

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?
