What this shows echem's Innovation Score is 55.2/100 (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 echem?

Each dot is one of echem’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). echem’s own 12.9 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where echem's grants concentrate

eChem Solutions Corp. is a focused PatentsView assignee: 23 CPC subclasses with 50% of grants classified under G03F (Photomechanical Production OF Textured OR Patterned Surfaces, e.g. FOR Printing, FOR Processing OF Semiconductor DEVICES; Materials THEREFOR; Originals THEREFOR; Apparatus Specially Adapted THEREFOR;). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2015. By volume, echem sits between Zhejiang University OF Science AND Technology and phenox GmbH.

echem's three-year grant acceleration

eChem Solutions Corp. shows 10 grants in 2022–2024 against only 1 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.
