What this shows Hitachi's Innovation Score is 41.8/100 (top 32% 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 Hitachi?

Each dot is one of Hitachi’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). Hitachi’s own 9.5 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hitachi's grants concentrate

Hitachi Industrial Products, Ltd. is a focused PatentsView assignee: 25 CPC subclasses with 34.5% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2023. By volume, Hitachi sits between Halo Microelectronics International and Intertape Polymer Corp..

Hitachi's three-year grant acceleration

Hitachi Industrial Products, Ltd. shows 13 grants in 2022–2024 against only 13 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.
