What this shows COX's Innovation Score is 37.2/100 (top 44% 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 COX?

Each dot is one of COX’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). COX’s own 18.3 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where COX's grants concentrate

COX Powertrain Limited is a focused PatentsView assignee: 15 CPC subclasses with 73.3% of grants classified under F02B (Internal-combustion Piston ENGINES; Combustion Engines IN General). Peak complete grant year is 2021 (7 grants) versus a trough of 1 in 2016. By volume, COX sits between Cole-parmer Instrument Company LLC and Canary Connect, Inc..

COX's three-year grant acceleration

COX Powertrain Limited shows 4 grants in 2022–2024 against only 9 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.
