What this shows Kuraray's Innovation Score is 48.6/100 (top 16% 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 Kuraray?

Each dot is one of Kuraray’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). Kuraray’s own 16.3 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kuraray's grants concentrate

Kuraray Europe GmbH is a focused PatentsView assignee: 24 CPC subclasses with 94.3% 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). Peak complete grant year is 2022 (6 grants) versus a trough of 1 in 2016. By volume, Kuraray sits between Koncept Technologies, Inc. and Logistics and Supply Chain MultiTech R&D Centre Limited.

Kuraray's three-year grant acceleration

Kuraray Europe GmbH shows 11 grants in 2022–2024 against only 8 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.
