What this shows Ebara's Innovation Score is 45.2/100 (top 24% 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 Ebara's grants concentrate

Ebara Environmental Plant Co., Ltd. is a focused PatentsView assignee: 17 CPC subclasses with 33.3% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). By volume, Ebara sits between Easydial Inc. and ECI Technology, Inc..

Ebara's three-year grant acceleration

Ebara Environmental Plant Co., Ltd. shows 4 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.
