What this shows Xiamen's Innovation Score is 36.0/100 (top 48% 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 Xiamen?

Each dot is one of Xiamen’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). Xiamen’s own 18.2 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Xiamen's grants concentrate

Xiamen Sanan Integrated Circuit Co., Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 75% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2019. By volume, Xiamen sits between X-Nav Technologies, LLC and Xometry, Inc..

Xiamen's three-year grant acceleration

Xiamen Sanan Integrated Circuit Co., Ltd. shows 5 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.
