What this shows Esol's Innovation Score is 41.7/100 (top 32% 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 Esol?

Each dot is one of Esol’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). Esol’s own 8.7 claims/patent is at or below the 11.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Esol's grants concentrate

Esol, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 81.8% 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 (6 grants) versus a trough of 1 in 2024. By volume, Esol sits between EOS of North America, Inc. and Eurosets S.R.L..

Esol's three-year grant acceleration

Esol, Inc. shows 7 grants in 2022–2024 against only 0 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.
