What this shows Chiba's Innovation Score is 44.2/100 (top 26% 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 Chiba?

Each dot is one of Chiba’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). Chiba’s own 9.1 claims/patent is ABOVE the 7.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Chiba's grants concentrate

Chiba Institute OF Technology is a focused PatentsView assignee: 22 CPC subclasses with 41.7% of grants classified under G05D (Systems FOR Controlling OR Regulating Non-electric Variables). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2016. By volume, Chiba sits between CFA Properties, Inc. and Chukyo Medical Co., Inc..

Chiba's three-year grant acceleration

Chiba Institute OF Technology shows 6 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.
