What this shows Sekisui's Innovation Score is 57.1/100 (top 5% 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 Sekisui?

Each dot is one of Sekisui’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). Sekisui’s own 8.9 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sekisui's grants concentrate

Sekisui House, Ltd. is a focused PatentsView assignee: 31 CPC subclasses with 50% of grants classified under E04B (General Building CONSTRUCTIONS; Walls, e.g. PARTITIONS; ROOFS; FLOORS; CEILINGS; Insulation OR Other Protection OF Buildings). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2021. By volume, Sekisui sits between ResMed R&D Germany GmbH and SMR Inventec, LLC.

Sekisui's three-year grant acceleration

Sekisui House, Ltd. shows 20 grants in 2022–2024 against only 1 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.
