What this shows I/o's Innovation Score is 45.8/100 (top 22% 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 I/o?

Each dot is one of I/o’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). I/o’s own 21.3 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where I/o's grants concentrate

I/O Controls Corporation is a focused PatentsView assignee: 23 CPC subclasses with 35.7% of grants classified under B60Q (Arrangement OF Signalling OR Lighting Devices, THE Mounting OR Supporting Thereof OR Circuits Therefor, FOR Vehicles IN General). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2017. By volume, I/o sits between Hyundai Electric & Energy Systems Co., Ltd. and Illumisonics Inc..

I/o's three-year grant acceleration

I/O Controls Corporation 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.
