What this shows Rayence's Innovation Score is 34.6/100 (48th 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 Rayence?

Each dot is one of Rayence’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). Rayence’s own 10.5 claims/patent is at or below the 16.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rayence's grants concentrate

Rayence Co., Ltd. is a focused PatentsView assignee: 18 CPC subclasses with 53.1% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2018 (9 grants) versus a trough of 1 in 2021. By volume, Rayence sits between Promethean Limited and Raindance Technologies, Inc..

Rayence's three-year grant acceleration

Rayence Co., Ltd. shows 2 grants in 2022–2024 against only 11 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.
