Where Chongqing's grants concentrate

Chongqing HKC Optoelectronics is a focused PatentsView assignee: 7 CPC subclasses with 77.8% of grants classified under G09G (Arrangements OR Circuits FOR Control OF Indicating Devices Using Static Means TO Present Variable Information). Peak complete grant year is 2021 (5 grants) versus a trough of 1 in 2022. By volume, Chongqing sits between Chef Software, Inc. and Christmas Northeast, Inc..

Chongqing's three-year grant acceleration

Chongqing HKC Optoelectronics shows 1 grants in 2022–2024 against only 8 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.
