What this shows Hitachi's Innovation Score is 73.5/100 (top 1% 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.

How Hitachi's grant cadence moved

Grant history spans 2021–2025. Across complete PatentsView years, output peaked in 2022 at 89 grants and bottomed in 2024 at 4. Lead class G01R accounts for 22.3% of the portfolio across 82 subclasses. Volume neighbours: Csmc Technologies Fab2 Co., Ltd. (#2,193) and Synaptive Medical (BARBADOS) Inc. (#2,201).

Hitachi's three-year grant acceleration

Hitachi Energy Switzerland AG shows 171 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.
