What this shows Light's Innovation Score is 45.5/100 (top 23% 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 Light?

Each dot is one of Light’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). Light’s own 14.7 claims/patent is ABOVE the 11.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Light's grants concentrate

Light Corp Inc. is a focused PatentsView assignee: 12 CPC subclasses with 33.3% 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 2020. By volume, Light sits between Ledup Manufacturing Group Limited and Linyi Huadong Pet Supplies Co., Ltd.

Light's three-year grant acceleration

Light Corp Inc. shows 7 grants in 2022–2024 against only 3 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.
