== PatentTODO Situationlist in(now 2012done!) ==

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.

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)

The article says "IDEA is patented in Austria, France, Germany...". you cannot patent software (or any other algorithms) in germany....

:: I'll add them to the to-do list anyway. [[User:Matt Crypto|— Matt]] 23:24, 27 Nov 2004 (UTC)

::: I have added an image showing the transformation round. [[User:Danielap48|danielap48]] 02:04, 19 Oct 2006 (UTC)

The IDEA applet link does not appear too useful, not in English and I saw no way to run a simulation.--[[User:Billymac00|Billymac00]] ([[User talk:Billymac00|talk]]) 19:24, 4 January 2009 (UTC)

== Patent expiration date ==

Line 88 ⟶ 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 ⟶ 163:

Given that it is now after Jan 7, 2012, is it safe to say that under any interpretation, the IDEA patent has now expired in the US? [[User:Riordanmr|Riordanmr]] ([[User talk:Riordanmr|talk]]) 18:58, 16 February 2012 (UTC)

== Patent Situation in 2012 ==

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.
