ALEXANDRIA, Va., May 5 -- United States Patent no. 12,618,331, issued on May 5, was assigned to Massachusetts Institute of Technology (Cambridge, Mass.).

"Discrete macroscopic metamaterial systems" was invented by Benjamin Jenett (Cambridge, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A construction system for mechanical metamaterials based on discrete assembly of a finite set of modular, mass-produced parts. A modular construction scheme enables a range of mechanical metamaterial properties to be achieved, including rigid, compliant, auxetic and chiral, all of which are assembled with a consistent process across part types, thereby expanding the functionality and accessibility of this approach.
