This dataset captures 10 patent families published against a search string targeting reconfigurable unit cells, metasurface antennas, tunable reflectarrays and unit-cell design within the H01Q antenna classification. That is a small, still-forming corpus rather than a mature one. Because publication lags filing by roughly 18 months, the true number of filings already made but not yet published is almost certainly higher, particularly for 2025 and 2026.

The tracked assignee set includes Dell Products L.P. (Dell), Xiangtan University, Tsinghua University, The Trustees of Princeton University, Corning Research and Development Corporation and Nanjing University of Science and Technology, alongside Huawei Technologies as the assignee behind the featured representative filing. None of these institutions logged a filing in the latest tracked year, so momentum across the named leaders is currently flat rather than concentrated in one player.

WO2024146683A1, filed by Huawei Technologies, claims a reconfigurable intelligent surface built from a linear array of unit cells, where each unit cell has a graphene layer on a silicon substrate that reflects EM radiation at an amplitude depending on the graphene layer’s chemical potential, controlled by a switching controller. It is a specific implementation route — graphene-on-silicon chemical-potential switching — rather than a claim over RIS antennas generally. Designs using MEMS actuation, liquid crystal, or PIN-diode switching for amplitude control sit outside its literal scope.
