What this shows Sien's Innovation Score is 48.9/100 (top 16% 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 Sien?
Each dot is one of Sien’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). Sien’s own 11.2 claims/patent is at or below the 13.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where Sien's grants concentrate
SiEn (QingDao) Integrated Circuits Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 82.6% of grants classified under H10D (Inorganic Electric Semiconductor Devices). Peak complete grant year is 2024 (11 grants) versus a trough of 3 in 2022. By volume, Sien sits between SentriLock, LLC and Smiths Detection Montreal Inc..
Sien's three-year grant acceleration
SiEn (QingDao) Integrated Circuits Co., Ltd. shows 18 grants in 2022–2024 against only 4 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.
