What this shows Hyundai's Innovation Score is 32.5/100 (41st 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 Hyundai?

Each dot is one of Hyundai’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). Hyundai’s own 9.3 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hyundai's grants concentrate

Hyundai Sungwoo Casting Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 62.5% of grants classified under B60B (Vehicle Wheels ; CASTORS; Axles FOR Wheels OR CASTORS; Increasing Wheel Adhesion). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2018. By volume, Hyundai sits between HypeVR and IAC Search & Media, Inc..

Hyundai's three-year grant acceleration

Hyundai Sungwoo Casting Co., Ltd. shows 3 grants in 2022–2024 against only 2 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.
