This link provides a liaison statement from the Open Mobile Alliance advising the IETF on policy changes relating to certain OMA specifications. As I understand it, OMA amended their IPR policy to require OMA members to license IPR needed to implement OMA specifications under RAND to non-members of OMA in addition to members of OMA, whereas the previous policy required licensing only to members of OMA.

This PDF lists the affected OMA specifications.
