What this shows Ya-man's Innovation Score is 29.3/100 (30th 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 Ya-man?

Each dot is one of Ya-man’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). Ya-man’s own 5.4 claims/patent is at or below the 10.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Ya-man's grants concentrate

Ya-man Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 29.4% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2015. By volume, Ya-man sits between Xoma (US) LLC and Zeroplus Technology Co., Ltd..

Ya-man's three-year grant acceleration

Ya-man Ltd. shows 6 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.
