What this shows SUN's Innovation Score is 26.1/100 (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 SUN?

Each dot is one of SUN’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). SUN’s own 6.6 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SUN's grants concentrate

SUN Same Enterprises Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 45.8% of grants classified under B41K (STAMPS; Stamping OR Numbering Apparatus OR Devices). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2019. By volume, SUN sits between Star Mesh LLC and Sanofi Pasteur SA.

SUN's three-year grant acceleration

SUN Same Enterprises Co., Ltd. shows 2 grants in 2022–2024 against only 8 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.
