What this shows Hoden's Innovation Score is 32.4/100 (41st percentile 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 Hoden?

Each dot is one of Hoden’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). Hoden’s own 7.3 claims/patent is at or below the 11.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hoden's grants concentrate

Hoden Seimitsi Kako Kenkyusho Co., Ltd. is a focused PatentsView assignee: 20 CPC subclasses with 41.7% of grants classified under Y10T (Technical Subjects Covered BY Former US Classification). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2015. By volume, Hoden sits between High Street TV (GROUP) Ltd. and Hongfujin Precision Electronics (CHENGDU) Co., Ltd..

Hoden's three-year grant acceleration

Hoden Seimitsi Kako Kenkyusho Co., Ltd. shows 3 grants in 2022–2024 against only 6 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.
