What this shows Hokuetsu's Innovation Score is 49.8/100 (top 14% 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 Hokuetsu?

Each dot is one of Hokuetsu’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). Hokuetsu’s own 15.0 claims/patent is ABOVE the 13.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Hokuetsu's grants concentrate

Hokuetsu Industries Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 37.5% of grants classified under B66F (Hoisting, Lifting, Hauling OR Pushing, NOT Otherwise Provided FOR, e.g. Devices Which Apply A Lifting OR Pushing Force Directly TO THE Surface OF A Load). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Hokuetsu sits between HMicro, Inc. and Hoppecke Batterien GMBH & Co. KG.

Hokuetsu's three-year grant acceleration

Hokuetsu Industries Co., Ltd. shows 3 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.
