What this shows Illum's Innovation Score is 30.7/100 (35th 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 Illum?

Each dot is one of Illum’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). Illum’s own 11.6 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Illum's grants concentrate

Illum Horticulture LLC is a focused PatentsView assignee: 13 CPC subclasses with 70% 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 2019 (9 grants) versus a trough of 1 in 2022. By volume, Illum sits between Interman Corporation and Ingrain, Inc..

Illum's three-year grant acceleration

Illum Horticulture LLC shows 1 grants in 2022–2024 against only 14 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.
