What this shows Kumho's Innovation Score is 30.3/100 (34th 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.

Does more volume mean deeper claims for Kumho?

Each dot is one of Kumho’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). Kumho’s own 8.2 claims/patent is at or below the 8.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kumho's grants concentrate

Kumho Electric, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 64.3% 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 2015 (5 grants) versus a trough of 1 in 2018. By volume, Kumho sits between Kiverdi, Inc. and Kabushiki Kaisha Ubitus.

Kumho's three-year grant acceleration

Kumho Electric, Inc. shows 1 grants in 2022–2024 against only 0 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.
