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 1.0 claims/patent is at or below the 13.9 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 Xutu Optical Glasses Co., Ltd. is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2024 (6 grants) versus a trough of 1 in 2022. By volume, Xiamen sits between Wild West Investments, LLC and Yield Microelectronics Corp..
Xiamen's three-year grant acceleration
Xiamen Xutu Optical Glasses Co., Ltd. shows 7 grants in 2022–2024 against only 0 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.
