What this shows The's Innovation Score is 45.7/100 (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.

Where The's grants concentrate

The Kansai Electric Power Co., Inc. is a focused PatentsView assignee: 34 CPC subclasses with 69.7% of grants classified under Y02C (Capture, Storage, Sequestration OR Disposal OF Greenhouse Gases [GHG]). Peak complete grant year is 2016 (9 grants) versus a trough of 1 in 2019. By volume, The sits between Textron Systems Corporation and Truth Hardware Corporation.

The's three-year grant acceleration

The Kansai Electric Power Co., Inc. shows 5 grants in 2022–2024 against only 4 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.
