What this shows Cormatrix's Innovation Score is 33.0/100 (43rd 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 Cormatrix?

Each dot is one of Cormatrix’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). Cormatrix’s own 7.2 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Cormatrix's grants concentrate

CorMatrix Cardiovascular, Inc. is a focused PatentsView assignee: 9 CPC subclasses with 88.2% of grants classified under A61L (Methods OR Apparatus FOR Sterilising Materials OR Objects IN GENERAL; Disinfection, Sterilisation OR Deodorisation OF AIR; Chemical Aspects OF Bandages, Dressings, Absorbent Pads OR Surgical ARTICLES;). Peak complete grant year is 2015 (21 grants) versus a trough of 4 in 2020. By volume, Cormatrix sits between Changzhou University and Given Imaging Ltd..

Cormatrix's three-year grant acceleration

CorMatrix Cardiovascular, Inc. shows 6 grants in 2022–2024 against only 15 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.
