Does more volume mean deeper claims for Ezisurg?

Each dot is one of Ezisurg’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). Ezisurg’s own 14.3 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ezisurg's grants concentrate

Ezisurg Medical Co., Ltd. is a focused PatentsView assignee: 1 CPC subclasses with 81.8% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (5 grants) versus a trough of 1 in 2021. By volume, Ezisurg sits between Excel-lens, Inc. and Eaton Cummins Automated Transmission Tech., LLC.

Ezisurg's three-year grant acceleration

Ezisurg Medical Co., Ltd. shows 9 grants in 2022–2024 against only 1 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.
