What this shows ES's Innovation Score is 32.2/100 (40th 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 13.8 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 Co., Ltd. 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 (4 grants) versus a trough of 2 in 2017. By volume, ES sits between EBT Medical, Inc. and EV Group GmbH.

ES's three-year grant acceleration

ES FiberVisions Co., Ltd. shows 4 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.
