What this shows EHC's Innovation Score is 33.9/100 (46th 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 EHC?

Each dot is one of EHC’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). EHC’s own 20.0 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where EHC's grants concentrate

EHC Canada, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2017. By volume, EHC sits between Ecole Nationale Superieure DE Mecanique ET DES Microtechniques (ENSMM) and EKO Health, Inc..

EHC's three-year grant acceleration

EHC Canada, Inc. shows 3 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.
