The article says "IDEA is patented in Austria, France, Germany...". you cannot patent software (or any other algorithms) in germany....
 
It's late and I'm tired, but this article lacks information on (a) the input/output transformation stage, and (b) the subkey generator. [[User:Raul654|→Raul654]] 03:19, Mar 21, 2004 (UTC)

Line 84 ⟶ 95:
 
:Non-RS web sites, such as forums and blogs, are mixed, with many referring to a 2012 expiration, but I suspect they get their info from this article. [http://crypto.junod.info/2011/05/ One site] is express about that: "the European patent protecting the IDEA (International Data Encryption Algorithm) block cipher has expired a few days ago, on May 16th, 2011, and hence felt into the public ___domain. Note however that, according to its Wikipedia page, the cipher is still protected in the US until January 7th, 2012." [[User:TJRC|TJRC]] ([[User talk:TJRC|talk]]) 00:05, 6 July 2011 (UTC)

==Explanation of U.S. patent expiration==
Line 167:
As others have noted, this article really needs to update the current patent situation. It's quite certain that the US patent has expired, but I hope someone is able to find a good source for the other patents granted.
