OpenJPEG has no such limitation. The library is distributed under a
vanilla BSD-license. So strictly speaking, OpenJPEG should be DFSG
Of course, it's possible to modify OpenJPEG until it infringes on a patent
somewhere, but that is possible with any software. We can each modify the
SL-Viewer until it infringes on a number of patents; that does not make
the SL-Viewer itself non-free.
OpenJPEG is a compliant Jpeg2000 implementation, having passed the P1C1 &
J2F conformance tests (though strict compliance is not required by the
patent declarations.) It's still possible that the Part 1 standard itself
is infringing on an unknown patent, but again that is a separate issue.
