    If you read a little further on the bzip pages, you would find that the
    reason bzip2 and bzip are incompatible, is because bzip was found to be
    patent-encumbered. The search for a better compression algorithm, that
    wasn't covered by a patent began...

    I actually remember when the original sources for the block sorter
    compression program were posted to comp.sources.misc or somewhere
    similar. The original impression most people had was 'this algorithm
    is a hoax... it can't compress...' And so, I believe, nobody bothered
    to patent it. :-)
