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.
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 12.9 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Sumitomo's grants concentrate
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's three-year grant acceleration
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.
