    bzip1 uses arithmetic encoding which is heavily patented. bzip2 uses
    huffman instead, which isn't, but is slightly (10% is often quoted)
    less efficient. I guess bzip3 could use range coding which is
    supposedly patent-free[1] and has similar compression ratio than
    arithmetic coding.

    OG.

    [1] I guess everything is in the way it is written, since I have a
    very hard time understand where the difference is between range coding
    and arithmetic coding.
