What this shows E-lead's Innovation Score is 41.5/100 (top 33% 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 E-lead?

Each dot is one of E-lead’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). E-lead’s own 11.9 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where E-lead's grants concentrate

E-lead Electronic Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 66.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2018 (9 grants) versus a trough of 1 in 2019. By volume, E-lead sits between Dicon Fiberoptics, Inc. and Eddy Current Limited Partnership.

E-lead's three-year grant acceleration

E-lead Electronic Co., Ltd. shows 5 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.
