What this shows Corneagen's Innovation Score is 38.9/100 (top 39% 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 Corneagen?

Each dot is one of Corneagen’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). Corneagen’s own 16.3 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 Corneagen's grants concentrate

CorneaGen is a focused PatentsView assignee: 7 CPC subclasses with 84.6% 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 2020. By volume, Corneagen sits between Converter Manufacturing, LLC and Cristal USA, Inc..

Corneagen's three-year grant acceleration

CorneaGen shows 8 grants in 2022–2024 against only 5 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.
