What this shows ART's Innovation Score is 27.0/100 (22nd 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 ART?

Each dot is one of ART’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). ART’s own 12.7 claims/patent is ABOVE the 9.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ART's grants concentrate

ART, Ltd. is a focused PatentsView assignee: 5 CPC subclasses with 87.5% 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 2016 (5 grants) versus a trough of 1 in 2017. By volume, ART sits between Aradigm Corporation and Asukanet Company, Ltd..

ART's three-year grant acceleration

ART, Ltd. shows 1 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.
