What this shows Tohoku's Innovation Score is 43.4/100 (top 28% 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 Tohoku?

Each dot is one of Tohoku’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). Tohoku’s own 10.9 claims/patent is at or below the 11.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tohoku's grants concentrate

Tohoku Techno Arch Co., Ltd. is a focused PatentsView assignee: 42 CPC subclasses with 30.3% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2015 (7 grants) versus a trough of 1 in 2022. By volume, Tohoku sits between THE SUN Lock Company Limited and Telcordia Technologies, Inc..

Tohoku's three-year grant acceleration

Tohoku Techno Arch Co., Ltd. shows 4 grants in 2022–2024 against only 15 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.
