What this shows Xiamen's Innovation Score is 35.9/100 (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 12.5 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Xiamen's grants concentrate

Xiamen SET Electronics Co., Ltd. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2016. By volume, Xiamen sits between Xcira, Inc and Xavier University of Louisiana.

Xiamen's three-year grant acceleration

Xiamen SET Electronics 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.
