What this shows Sumitomo's Innovation Score is 44.5/100 (top 25% 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 6.9 claims/patent is at or below the 18.9 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 Fine Polymer, Inc. is a focused PatentsView assignee: 43 CPC subclasses with 45.7% of grants classified under B32B (Layered Products, i.e. Products Built-up OF Strata OF Flat OR Non-flat, e.g. Cellular OR Honeycomb, Form). Peak complete grant year is 2016 (12 grants) versus a trough of 1 in 2018. By volume, Sumitomo sits between Smart Power Co., Ltd. and Sonatus, Inc..

Sumitomo's three-year grant acceleration

Sumitomo Electric Fine Polymer, Inc. shows 7 grants in 2022–2024 against only 12 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.
