Document: draft-ietf-ippm-active-passive-04.txt Reviewer: Brian Carpenter Review Date: 2015-12-16 IETF LC End Date: 2015-12-24 IESG Telechat date: Summary: Almost ready -------- Minor Issue: ------------ We note that [I-D.chen-ippm-coloring-based-ipfpm-framework] proposes a method similar to [I-D.tempia-opsawg-p3m], and ippm-list discussion indicates [I-D.chen-ippm-coloring-based-ipfpm-framework] may be covered by the same IPR as [I-D.tempia-opsawg-p3m]. I suggest removing the IPR comment. It may be an issue, but not for this draft. We generally avoid taking a position on IPR applicablity (in fact, our lawyer tells us not to do so).
