Following the great advice of @George White, i went on and checked patents against the PUBLIC PAIR database, to understand the flow between the applicant and the examiner, as well as the uk equivalent.
I stumbled upon this patent, and i do not understand the officer reply. He reports relevant patents showing lack of novelty. He also points out that the invention suggests something impossible and this should be enough for rejection afaik.
And yet, the patent has been published, not even a non-final rejection?
