What this shows Ontario's Innovation Score is 33.4/100 (44th 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 Ontario?

Each dot is one of Ontario’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). Ontario’s own 18.3 claims/patent is ABOVE the 13.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ontario's grants concentrate

Ontario Power Generation Inc. is a focused PatentsView assignee: 11 CPC subclasses with 66.7% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2020. By volume, Ontario sits between One Pass Innovators, LLC and Opiant Pharmaceuticals, Inc..

Ontario's three-year grant acceleration

Ontario Power Generation Inc. shows 2 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.
