What this shows RED's Innovation Score is 35.5/100 (top 49% 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 RED?

Each dot is one of RED’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). RED’s own 20.4 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where RED's grants concentrate

RED BOX Recorders Limited is a focused PatentsView assignee: 4 CPC subclasses with 80% 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 2022 (2 grants) versus a trough of 1 in 2019. By volume, RED sits between Realyagu Zone Co., Ltd. and Regenerx Biopharmaceuticals, Inc..

RED's three-year grant acceleration

RED BOX Recorders Limited shows 3 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.
