What this shows Ottawa's Innovation Score is 47.2/100 (top 19% 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 Ottawa?

Each dot is one of Ottawa’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). Ottawa’s own 16.7 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Ottawa's grants concentrate

Ottawa Hospital Research Institute is a focused PatentsView assignee: 26 CPC subclasses with 81.8% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2019. By volume, Ottawa sits between Ogeda SA and Paragon Semiconductor Lighting Technology Co., Ltd..

Ottawa's three-year grant acceleration

Ottawa Hospital Research Institute shows 5 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.
