Quite aside from the question of what the IESG should do about the
registration, my reading of this patent finds nothing novel.  Almost all
the claims (including the first one, upon which all others are based),
are essentially just claiming invention of multi-part mime, which
predated the application by several years.

Is there (should there be) a mechanism whereby the IETF or one of our
more corporate parents can file some challenge to the patent having been
issued?
