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 9.0 claims/patent is at or below the 16.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
How Sumitomo's grant cadence moved
Between 2020–2024, Sumitomo Electric Industries, Ltd. received 2,172 grants versus 1,902 in 2015–2019 (+14% equal-window velocity, above median growth).
