What this shows CHI's Innovation Score is 50.9/100 (top 12% 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 CHI?

Each dot is one of CHI’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). CHI’s own 10.5 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CHI's grants concentrate

CHI MEI Medical Center is a focused PatentsView assignee: 19 CPC subclasses with 53.8% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2016 (3 grants) versus a trough of 1 in 2017. By volume, CHI sits between Cequence Security, Inc. and Chubu University Educational Foundation.

CHI's three-year grant acceleration

CHI MEI Medical Center shows 4 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.
