What this shows Corin's Innovation Score is 37.0/100 (top 45% 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 Corin?

Each dot is one of Corin’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). Corin’s own 26.3 claims/patent is ABOVE the 9.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Corin's grants concentrate

Corin Limited is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, Corin sits between Core Products International, Inc. and Cosmax NS. Inc..

Corin's three-year grant acceleration

Corin Limited shows 1 grants in 2022–2024 against only 1 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.
