I'm not completely sure I agree here - it seems that it restricts
itself to self-defense against IPR attacks on an open standard.
However, the line is thin, and there's probably not a detailed
consensus about where to draw it in this particular area.

Agreed. So luckily we don't need any detailed flamewar over which
degree of anti-patent self-defense we allow a license to include.
And to Eric: This clause is non-free because it restricts
modifications. It does not allow modifications that change the code to
work with another format than jpeg. The DFSG requires the right to
make modifications, and does not permit any  restrictions on this
 Except certain restrictions for the purpose of preventing modified
versions from being falsely represented as being the work of the
original author, which we do traditionally accept as free.
