What this shows Kyowa's Innovation Score is 35.7/100 (top 49% 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 Kyowa?

Each dot is one of Kyowa’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). Kyowa’s own 11.2 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Kyowa's grants concentrate

Kyowa Leather Cloth Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 83.3% 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). By volume, Kyowa sits between Kusumoto Chemicals, Ltd. and Kanagawa Prefectural Hospital Organization.

Kyowa's three-year grant acceleration

Kyowa Leather Cloth Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
