What this shows Hitachi-lg's Innovation Score is 28.1/100 (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 Hitachi-lg?

Each dot is one of Hitachi-lg’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-lg’s own 8.4 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hitachi-lg's grants concentrate

Hitachi-lg Data Storage Korea, Inc. is a focused PatentsView assignee: 11 CPC subclasses with 40% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Hitachi-lg sits between Hanon Systems EFP Deutschland GMBH and Hugo Vogelsang Maschinenbau GMBH.

Hitachi-lg's three-year grant acceleration

Hitachi-lg Data Storage Korea, Inc. shows 1 grants in 2022–2024 against only 8 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.
