What this shows Estorm's Innovation Score is 26.1/100 (19th 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 Estorm?

Each dot is one of Estorm’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). Estorm’s own 7.9 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Estorm's grants concentrate

Estorm Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 87.5% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2018. By volume, Estorm sits between Epitronic Holdings PTE Ltd. and Evergreen Nursery.

Estorm's three-year grant acceleration

Estorm Co., Ltd. shows 3 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.
