What this shows Sumitomo's Innovation Score is 28.7/100 (28th percentile 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 9.2 claims/patent is at or below the 14.7 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 Electric Wintec, Inc. is a focused PatentsView assignee: 10 CPC subclasses with 77.8% of grants classified under H01B (CABLES; CONDUCTORS; INSULATORS; Selection OF Materials FOR Their Conductive, Insulating OR Dielectric Properties). Peak complete grant year is 2024 (3 grants) versus a trough of 1 in 2016. By volume, Sumitomo sits between STMicroelectronics Belgium and Sunshine Guojian Pharmaceutical (SHANGHAI) Co., Ltd..

Sumitomo's three-year grant acceleration

Sumitomo Electric Wintec, Inc. shows 3 grants in 2022–2024 against only 5 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.
