What this shows Fanlight's Innovation Score is 38.2/100 (top 41% 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 Fanlight?

Each dot is one of Fanlight’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). Fanlight’s own 9.9 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fanlight's grants concentrate

Fanlight Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 78.6% 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 2023 (3 grants) versus a trough of 1 in 2019. By volume, Fanlight sits between Evrio, Inc. and Feelux Co., Ltd..

Fanlight's three-year grant acceleration

Fanlight Co., Ltd. shows 8 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.
