What this shows Furukawa's Innovation Score is 40.1/100 (top 36% 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 Furukawa?

Each dot is one of Furukawa’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). Furukawa’s own 11.0 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Furukawa's grants concentrate

Furukawa Co., Ltd. is a focused PatentsView assignee: 28 CPC subclasses with 29.2% of grants classified under C30B (Single-crystal Growth ; Unidirectional Solidification OF Eutectic Material OR Unidirectional Demixing OF Eutectoid MATERIAL; Refining BY Zone-melting OF Material ; Production OF A Homogeneous Polycrys). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2017. By volume, Furukawa sits between FTI Group (HOLDING) Company Limited and Florensis B.V..

Furukawa's three-year grant acceleration

Furukawa Co., Ltd. shows 5 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.
