What this shows Sumitomo's Innovation Score is 64.0/100 (top 2% 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 23.1 claims/patent is ABOVE the 18.5 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 Pharma Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 82.5% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2023 (19 grants) versus a trough of 11 in 2022. By volume, Sumitomo sits between Siemens Healthcare Diagnostics Products GmbH and Therma-stor LLC.

Sumitomo's three-year grant acceleration

Sumitomo Pharma Co., Ltd. shows 49 grants in 2022–2024 against only 0 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.
