What this shows Cardex's Innovation Score is 38.7/100 (top 40% 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 Cardex?

Each dot is one of Cardex’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). Cardex’s own 18.8 claims/patent is ABOVE the 16.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cardex's grants concentrate

Cardex Systems Inc. is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under G07F (Coin-freed OR Like Apparatus). By volume, Cardex sits between Captron Electronic GmbH and Carefusion Switzerland 317 SÀRL.

Cardex's three-year grant acceleration

Cardex Systems Inc. shows 2 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.
