What this shows Hitachi's Innovation Score is 35.4/100 (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 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 9.7 claims/patent is at or below the 15.8 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 Information AND Telecommunication Engineering, Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 33.3% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2015 (9 grants) versus a trough of 1 in 2022. By volume, Hitachi sits between Goodrich Lighting Systems GmbH & Co. KG and Idex ASA.

Hitachi's three-year grant acceleration

Hitachi Information AND Telecommunication Engineering, Ltd. shows 1 grants in 2022–2024 against only 11 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.
