I've written to Gligor and Donescu (his mail address is bouncing though and I do not have another/current one). I've not received any replies as of today. Rogaway, like myself, is not sure if that patent actually relates to OCB. He's included it in his initial IPR statement on RFC 7253 [0] as a pre caution as far as I can tell. The patent by Gligor and Donescu will expire on 18th of January 2021.
