What this shows Gunze's Innovation Score is 47.7/100 (top 18% 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 Gunze?

Each dot is one of Gunze’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). Gunze’s own 6.1 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Gunze's grants concentrate

Gunze Limited is a focused PatentsView assignee: 40 CPC subclasses with 35% 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 2017 (6 grants) versus a trough of 3 in 2016. By volume, Gunze sits between GCP Applied Technologies Inc. and Heraeus Noblelight GMBH.

Gunze's three-year grant acceleration

Gunze Limited shows 12 grants in 2022–2024 against only 9 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.
