Where E-ray's grants concentrate

E-RAY Optoelectronics Technology Co., Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under H10K (ORGANIC ELECTRIC SOLID-STATE DEVICES). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, E-ray sits between Druggability Technologies IP Holdco Limited and EASY Sanitary Solutions B.v..

E-ray's three-year grant acceleration

E-RAY Optoelectronics Technology Co., Ltd. shows 1 grants in 2022–2024 against only 2 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.
