Well, software patents are valid only on very few Countries. People that live on a software-patent-free Country can keep using those protocols, if they can just upload a set of rules for a generic driver. On the other hand, a rule-hardcoded codec for a patented protocol cannot be inside Kernel, as this would restrict kernel distribution on those non-software-patent-free Countries.
