Where Fujian's grants concentrate

Fujian Jing'an Optoelectronics Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under C30B (Single-crystal Growth ; Unidirectional Solidification OF Eutectic Material OR Unidirectional Demixing OF Eutectoid MATERIAL; Refining BY Zone-melting OF Material ; Production OF A Homogeneous Polycrys). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2020. By volume, Fujian sits between Ftlab Co., Ltd. and Fujitsu Semiconductor Memory Solution Limited.

Fujian's three-year grant acceleration

Fujian Jing'an Optoelectronics Co., Ltd. shows 4 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.
