//  RFC 3492 - Punycode: A Bootstring encoding of Unicode
//          for Internationalized Domain Names in Applications (IDNA)

is there and working.

As for patents, well, I can't be sure, but the whole process is described by 
the above RFCs in a lot of detail. They don't mention any patents. And 
libidn's code follows those instructions to the mark.

I don't know what got into you to come up with a conspiracy theory, but I feel
