What this shows Sumitomo's Innovation Score is 42.8/100 (top 30% 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 Sumitomo's grants concentrate

Sumitomo SHI FW Energia Oy is a focused PatentsView assignee: 20 CPC subclasses with 58.8% of grants classified under F23C (Methods OR Apparatus FOR Combustion Using Fluid Fuel OR Solid Fuel Suspended IN ; A Carrier GAS OR; AIR). Peak complete grant year is 2018 (4 grants) versus a trough of 2 in 2022. By volume, Sumitomo sits between SpeedInnov and Swimways Corporation.

Sumitomo's three-year grant acceleration

Sumitomo SHI FW Energia Oy shows 5 grants in 2022–2024 against only 6 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.
