What this shows Honshu's Innovation Score is 28.2/100 (26th 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 Honshu?

Each dot is one of Honshu’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). Honshu’s own 2.6 claims/patent is at or below the 9.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Honshu's grants concentrate

Honshu Chemical Industry Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 65% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2016. By volume, Honshu sits between Hirschmann Automation AND Control GMBH and Husco International, Inc..

Honshu's three-year grant acceleration

Honshu Chemical Industry Co., Ltd. shows 4 grants in 2022–2024 against only 7 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.
