Just for the record: 

The primary reason GnuPG was written is to avoid exactly that patent
claim.  I am obviously not very lucky to hear that money is put into
the chests of the patent holder by means of software written to avoid

There is no technical reason for IDEA and actually it is a weaker
cipher than the modern ones (i.e. AES or Twofish) at least in terms of
block size.,
