What this shows Grid4c's Innovation Score is 29.1/100 (29th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Grid4c's grants concentrate

Grid4c Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Grid4c sits between Great GO Cycles Inc. and Gripwiq Holding ApS.

Grid4c's three-year grant acceleration

Grid4c Ltd. shows 1 grants in 2022–2024 against only 5 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
