What this shows Hankook's Innovation Score is 55.5/100 (top 7% 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 Hankook?

Each dot is one of Hankook’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). Hankook’s own 4.8 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 Hankook's grants concentrate

Hankook Tire & Technology Co., Ltd. is a focused PatentsView assignee: 27 CPC subclasses with 48.3% of grants classified under B60C (Vehicle TYRES; Tyre INFLATION; Tyre CHANGING; Connecting Valves TO Inflatable Elastic Bodies IN GENERAL; Devices OR Arrangements Related TO Tyres). Peak complete grant year is 2023 (24 grants) versus a trough of 3 in 2021. By volume, Hankook sits between F.S.KOREA Industries Inc. and Hyperloop Technologies, Inc..

Hankook's three-year grant acceleration

Hankook Tire & Technology Co., Ltd. shows 52 grants in 2022–2024 against only 3 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.
