What this shows Cardea's Innovation Score is 38.0/100 (top 42% 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 Cardea?

Each dot is one of Cardea’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). Cardea’s own 19.1 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cardea's grants concentrate

Cardea Bio, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 83.3% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2021 (4 grants) versus a trough of 2 in 2022. By volume, Cardea sits between Caldera Medical, Inc. and Cascade Designs, Inc..

Cardea's three-year grant acceleration

Cardea Bio, Inc. shows 5 grants in 2022–2024 against only 4 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.
