Where Cellular's grants concentrate

Cellular South, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 100% of grants classified under G10L (Speech Analysis Techniques OR Speech SYNTHESIS; Speech RECOGNITION; Speech OR Voice Processing TECHNIQUES; Speech OR Audio Coding OR Decoding). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Cellular sits between Cefo Co., Ltd. and Centrix Aerospace LLC.

Cellular's three-year grant acceleration

Cellular South, Inc. shows 2 grants in 2022–2024 against only 3 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.
