What this shows ES's Innovation Score is 30.0/100 (33rd percentile 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 ES?

Each dot is one of ES’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). ES’s own 6.7 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where ES's grants concentrate

ES FiberVisions Hong Kong Limited is a focused PatentsView assignee: 14 CPC subclasses with 90% of grants classified under D01F (Chemical Features IN THE Manufacture OF Artificial Filaments, Threads, Fibres, Bristles OR RIBBONS; Apparatus Specially Adapted FOR THE Manufacture OF Carbon Filaments). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, ES sits between Epiroc Drilling Tools Aktiebolag and Etalim Inc..

ES's three-year grant acceleration

ES FiberVisions Hong Kong Limited shows 2 grants in 2022–2024 against only 3 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.
