What this shows Eoflow's Innovation Score is 47.3/100 (top 19% 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 Eoflow?

Each dot is one of Eoflow’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). Eoflow’s own 7.1 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Eoflow's grants concentrate

EOFlow Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 66.7% of grants classified under A61M (Devices FOR Introducing Media Into, OR Onto, THE Body ; Devices FOR Transducing Body Media OR FOR Taking Media From THE Body ; Devices FOR Producing OR Ending Sleep OR Stupor). Peak complete grant year is 2024 (10 grants) versus a trough of 2 in 2021. By volume, Eoflow sits between Distalmotion SA and Encite LLC.

Eoflow's three-year grant acceleration

EOFlow Co., Ltd. shows 24 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.
