What this shows Eliiy's Innovation Score is 39.1/100 (top 39% 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 Eliiy?

Each dot is one of Eliiy’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). Eliiy’s own 14.3 claims/patent is at or below the 20.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Eliiy's grants concentrate

Eliiy Power Co., Ltd. is a focused PatentsView assignee: 11 CPC subclasses with 90.9% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2015. By volume, Eliiy sits between Dorf Ketal Chemicals (India) Private Limited and Enterpriseweb LLC.

Eliiy's three-year grant acceleration

Eliiy Power Co., Ltd. shows 6 grants in 2022–2024 against only 5 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.
