What this shows Iljin's Innovation Score is 45.4/100 (top 23% 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 Iljin?

Each dot is one of Iljin’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). Iljin’s own 12.8 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Iljin's grants concentrate

Iljin Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 95.8% of grants classified under B60G (Vehicle Suspension Arrangements). Peak complete grant year is 2023 (7 grants) versus a trough of 1 in 2016. By volume, Iljin sits between Huntington Ingalls Incorporated and Intelligent Intellectual Property Holdings 2 LLC.

Iljin's three-year grant acceleration

Iljin Co., Ltd. shows 12 grants in 2022–2024 against only 6 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.
