What this shows Raphas's Innovation Score is 26.0/100 (19th 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 Raphas?

Each dot is one of Raphas’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). Raphas’s own 7.0 claims/patent is at or below the 13.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Raphas's grants concentrate

Raphas Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 80% 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 2019 (2 grants) versus a trough of 1 in 2020. By volume, Raphas sits between Raicam Driveline S.R.L. and Ravas Europe B.V..

Raphas's three-year grant acceleration

Raphas Co., Ltd. shows 2 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.
