What this shows Eternal's Innovation Score is 43.6/100 (top 28% 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 Eternal?

Each dot is one of Eternal’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). Eternal’s own 12.7 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Eternal's grants concentrate

Eternal Materials Co., Ltd. is a focused PatentsView assignee: 33 CPC subclasses with 38.8% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2024. By volume, Eternal sits between Danfoss Power Solutions GMBH & Co. OHG and Editas Medicine, Inc..

Eternal's three-year grant acceleration

Eternal Materials Co., Ltd. shows 6 grants in 2022–2024 against only 19 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.
