What this shows Taisei's Innovation Score is 32.6/100 (42nd 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 Taisei?

Each dot is one of Taisei’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). Taisei’s own 11.6 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taisei's grants concentrate

Taisei Corporation is a focused PatentsView assignee: 14 CPC subclasses with 44.4% of grants classified under Y02W (Climate Change Mitigation Technologies Related TO Wastewater Treatment OR Waste Management). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, Taisei sits between TWO Cells Co., Ltd. and Tarsus Pharmaceuticals, Inc..

Taisei's three-year grant acceleration

Taisei Corporation shows 2 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.
