What this shows Sienna's Innovation Score is 24.9/100 (16th 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 Sienna?

Each dot is one of Sienna’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). Sienna’s own 4.8 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sienna's grants concentrate

Sienna Group Corporation is a focused PatentsView assignee: 4 CPC subclasses with 10% of grants classified under A47G (Household OR Table Equipment). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Sienna sits between Shin Ying Entpr Co., Ltd. and Signifi Solutions Inc..

Sienna's three-year grant acceleration

Sienna Group Corporation shows 1 grants in 2022–2024 against only 0 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.
