What this shows Sansi's Innovation Score is 21.6/100 (9th 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 Sansi?

Each dot is one of Sansi’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). Sansi’s own 6.3 claims/patent is at or below the 15.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sansi's grants concentrate

Sansi Optoelectronics Technology (Shanghai) Co. Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under F21V (Functional Features OR Details OF Lighting Devices OR Systems THEREOF; Structural Combinations OF Lighting Devices With Other Articles, NOT Otherwise Provided FOR). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2019. By volume, Sansi sits between Salco Products, Inc. and Scheidt & Bachmann GmbH.

Sansi's three-year grant acceleration

Sansi Optoelectronics Technology (Shanghai) Co. Ltd. shows 1 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.
