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.

Does more volume mean deeper claims for Sumitomo?

Each dot is one of Sumitomo’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). Sumitomo’s own 19.1 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
