Where Wuhan's grants concentrate

Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences is a focused PatentsView assignee: 13 CPC subclasses with 36.4% of grants classified under G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). Peak complete grant year is 2020 (3 grants) versus a trough of 1 in 2018. By volume, Wuhan sits between Withsecure Corporation and Waterway Plastics.

Wuhan's three-year grant acceleration

Wuhan Institute OF Physics AND Mathematics, Chinese Academy OF Sciences shows 1 grants in 2022–2024 against only 7 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.
