What this shows Sumitomo's Innovation Score is 45.0/100 (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.
Sumitomo Heavy Industries Construction Cranes Co., Ltd. is a focused PatentsView assignee: 26 CPC subclasses with 87.5% of grants classified under B66C (CRANES; Load-engaging Elements OR Devices FOR Cranes, Capstans, Winches, OR Tackles). Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2022. By volume, Sumitomo sits between Spire Global, Inc. and System Ceramics S.P.A..
Sumitomo Heavy Industries Construction Cranes Co., Ltd. shows 11 grants in 2022–2024 against only 9 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.
