Campvalley's three-year grant acceleration

Campvalley (Xiamen) Co., Ltd. shows 8 grants in 2022–2024 against only 13 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.
