Non-applicability of the Gaborit&Aguilar-Melchor patent to Kyber and Saber

Vadim Lyubashevsky and Damien Stehlé

Abstract: In the context of the NIST post-quantum cryptography project, there have been claims that the Gaborit&Aguilar-Melchor patent could apply to the Kyber and Saber encryption schemes. In this short note, we argue that these claims are in contradiction with the potential validity of the patent.
