What this shows Hokuyo's Innovation Score is 35.5/100 (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 Hokuyo?

Each dot is one of Hokuyo’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). Hokuyo’s own 11.3 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hokuyo's grants concentrate

Hokuyo Automatic Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 58.3% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Hokuyo sits between Hitachi Powdered Metals Co., Ltd. and Hsbc Technology & Services (USA) Inc..

Hokuyo's three-year grant acceleration

Hokuyo Automatic Co., Ltd. shows 2 grants in 2022–2024 against only 3 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.
