What this shows Honda's Innovation Score is 41.4/100 (top 33% 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 Honda?

Each dot is one of Honda’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). Honda’s own 8.8 claims/patent is at or below the 11.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Honda's grants concentrate

Honda Foundry Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under B22C (Foundry Moulding). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2017. By volume, Honda sits between Hokusan Co., Ltd. and Hoosier Energy Rural Electric Cooperative, Inc..

Honda's three-year grant acceleration

Honda Foundry 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.
