Where Rayotek's grants concentrate

Rayotek Scientific, Inc. is a focused PatentsView assignee: 12 CPC subclasses with 25% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2015. By volume, Rayotek sits between Ranbaxy Laboratories Limited and Reapplix APS.

Rayotek's three-year grant acceleration

Rayotek Scientific, Inc. shows 1 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.
