Patenting the impossible

Jean-loup Gailly (author of gzip!) dissects US Patent 5,533,051 on ‘compression of random data’.
The title immediately raises suspicion as it’s impossible to compress truly random data.
Anyone with a background in mathematics or information theory is probably familiar with the relevant proofs already, but the article does a great job of explaining the arguments and addressing each patent claim so I recommend checking it out.
