What this shows ilumisys's Innovation Score is 41.9/100 (top 32% 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.

Where ilumisys's grants concentrate

iLumisys, Inc. is a focused PatentsView assignee: 21 CPC subclasses with 71.9% of grants classified under F21K (Non-electric Light Sources Using LUMINESCENCE; Light Sources Using ELECTROCHEMILUMINESCENCE; Light Sources Using Charges OF Combustible MATERIAL; Light Sources Using Semiconductor Devices AS Light-gen). Peak complete grant year is 2017 (14 grants) versus a trough of 3 in 2022. By volume, ilumisys sits between X-fab Semiconductor Foundries GMBH and AbbVie Biotechnology Ltd..

ilumisys's three-year grant acceleration

iLumisys, Inc. shows 3 grants in 2022–2024 against only 18 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.
