What this shows Sun's Innovation Score is 27.9/100 (25th 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 4.3 claims/patent is at or below the 18.1 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 Pleasure Company Limited is a focused PatentsView assignee: 14 CPC subclasses with 33.3% of grants classified under A47C (CHAIRS; SOFAS; Beds). Peak complete grant year is 2016 (4 grants) versus a trough of 1 in 2015. By volume, Sun sits between StemCell Technologies Inc. and Synvasive Technology, Inc..

Sun's three-year grant acceleration

Sun Pleasure Company Limited shows 2 grants in 2022–2024 against only 7 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.
