What this shows Cellular's Innovation Score is 29.5/100 (31st percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Cellular?

Each dot is one of Cellular’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Cellular’s own 15.0 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
