Does more volume mean deeper claims for Calgary?
Each dot is one of Calgary’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). Calgary’s own 18.6 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 Calgary's grants concentrate
Calgary Scientific Inc. is a focused PatentsView assignee: 12 CPC subclasses with 65.2% of grants classified under H04L (Transmission OF Digital Information, e.g. Telegraphic Communication). Peak complete grant year is 2018 (11 grants) versus a trough of 1 in 2022. By volume, Calgary sits between Changsha University OF Science AND Technology and Dental Monitoring.
Calgary's three-year grant acceleration
Calgary Scientific Inc. shows 1 grants in 2022–2024 against only 15 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.
