What this shows Nanogrid's Innovation Score is 41.6/100 (top 33% 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.

Does more volume mean deeper claims for Nanogrid?

Each dot is one of Nanogrid’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Nanogrid’s own 18.6 claims/patent is ABOVE the 8.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nanogrid's grants concentrate

Nanogrid Limited is a focused PatentsView assignee: 11 CPC subclasses with 71.4% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2017. By volume, Nanogrid sits between NAC International Inc. and Nantong YA TAI Candle Arts & Crafts Co., Ltd..

Nanogrid's three-year grant acceleration

Nanogrid Limited shows 7 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.
