What this shows Sino-american's Innovation Score is 34.0/100 (46th 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 Sino-american?

Each dot is one of Sino-american’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). Sino-american’s own 10.4 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 Sino-american's grants concentrate

Sino-American Silicon Products Inc. is a focused PatentsView assignee: 17 CPC subclasses with 87% of grants classified under C30B (Single-crystal Growth ; Unidirectional Solidification OF Eutectic Material OR Unidirectional Demixing OF Eutectoid MATERIAL; Refining BY Zone-melting OF Material ; Production OF A Homogeneous Polycrys). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2020. By volume, Sino-american sits between Shanghai Hoto Technology Co., Ltd. and Sony Advanced Visual Sensing AG.

Sino-american's three-year grant acceleration

Sino-American Silicon Products Inc. shows 1 grants in 2022–2024 against only 3 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.
