What this shows Ebara's Innovation Score is 47.4/100 (top 19% 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 Refrigeration Equipment & Systems Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 83.3% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). By volume, Ebara sits between Eaton Industries (AUSTRIA) GMBH and ECO Environmental Energy Research Institute Limited.

Ebara's three-year grant acceleration

Ebara Refrigeration Equipment & Systems 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.
