What this shows Sunstar's Innovation Score is 37.5/100 (top 43% 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 Sunstar?

Each dot is one of Sunstar’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). Sunstar’s own 12.5 claims/patent is at or below the 15.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sunstar's grants concentrate

Sunstar Suisse SA is a focused PatentsView assignee: 18 CPC subclasses with 46.4% of grants classified under A61C (DENTISTRY; Apparatus OR Methods FOR Oral OR Dental Hygiene). Peak complete grant year is 2020 (8 grants) versus a trough of 1 in 2021. By volume, Sunstar sits between Spectra Systems Corporation and Taiwan Liposome Co., Ltd..

Sunstar's three-year grant acceleration

Sunstar Suisse SA shows 6 grants in 2022–2024 against only 12 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.
