What this shows Keisokugiken's Innovation Score is 31.5/100 (38th 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 Keisokugiken?

Each dot is one of Keisokugiken’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). Keisokugiken’s own 17.0 claims/patent is ABOVE the 14.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Keisokugiken's grants concentrate

Keisokugiken Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under G06T (Image Data Processing OR Generation, IN General). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2022. By volume, Keisokugiken sits between Kedu Electric Co., Ltd. and Keyxentic Inc..

Keisokugiken's three-year grant acceleration

Keisokugiken Co., Ltd. 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.
