Where Qinghai's grants concentrate

Qinghai Institute OF Salt Lakes, Chinese Academy OF Sciences is a focused PatentsView assignee: 16 CPC subclasses with 50% of grants classified under C01F (Compounds OF THE Metals Beryllium, Magnesium, Aluminium, Calcium, Strontium, Barium, Radium, Thorium, OR OF THE Rare-earth Metals). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2021. By volume, Qinghai sits between Pulse Health LLC and Quantalrf AG.

Qinghai's three-year grant acceleration

Qinghai Institute OF Salt Lakes, Chinese Academy OF Sciences shows 7 grants in 2022–2024 against only 1 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.
