The same scientist, Salvatore Cezar Pais, also patented what reads suspiciously like an EmDrive: https://patents.justia.com/patent/10144532 I'm curious what any physicists here have to say.

I'm guessing that this superconductor concept hasn't actually been reduced to a prototype. Unfortunately, per the USPTO, "[a]n applicant need not have actually reduced the invention to practice prior to filing." https://www.uspto.gov/web/offices/pac/mpep/s2164.html#d0e215... A patent can simply describe a so-called prophetic example. "A prophetic example describes an embodiment of the invention based on predicted results rather than work actually conducted or results actually achieved." Id.

EDIT: Yep. The abstract from this 2019 paper, "Room Temperature Superconducting System for use on a Hybrid Aerospace-Undersea Craft", clearly (IMO) says the concept is as-yet unconfirmed. https://arc.aiaa.org/doi/abs/10.2514/6.2019-0869

Sooo ... would this be one of those "submarine" patents?
