What this shows Elfi-tech's Innovation Score is 27.2/100 (23rd 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 Elfi-tech?

Each dot is one of Elfi-tech’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). Elfi-tech’s own 12.8 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Elfi-tech's grants concentrate

Elfi-tech Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 83.3% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2020. By volume, Elfi-tech sits between Elec-tech International Co., Ltd. and Elvy Inc..

Elfi-tech's three-year grant acceleration

Elfi-tech 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.
