What this shows CTL's Innovation Score is 33.6/100 (45th 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 CTL?

Each dot is one of CTL’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). CTL’s own 17.8 claims/patent is ABOVE the 16.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CTL's grants concentrate

CTL Medical Corporation is a focused PatentsView assignee: 4 CPC subclasses with 76.5% of grants classified under A61F (Filters Implantable Into Blood VESSELS; PROSTHESES; Devices Providing Patency TO, OR Preventing Collapsing OF, Tubular Structures OF THE Body, e.g. STENTS; Orthopaedic, Nursing OR Contraceptive Device). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2022. By volume, CTL sits between Cosemi Technologies, Inc. and Cabeau, Inc..

CTL's three-year grant acceleration

CTL Medical Corporation shows 7 grants in 2022–2024 against only 8 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.
