    I'm not a lawyer, but it seems that if that were the case, it would be
    rather counterproductive to list pages and pages of specific claims.

    Maybe you are right and I can create an alternative encoding that, say,
    treats the range U+0020 through U+003F the same way that BOCU-1 treats
    U+0020 alone. Sometimes it would yield better compresson, sometimes

    The rest of your post, including the international scope of patents and
    the potential conflict between IBM's patent and the X license, I would
    not touch without legal advice.
