What this shows Canada's Innovation Score is 32.1/100 (40th 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 Canada?

Each dot is one of Canada’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). Canada’s own 12.1 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Canada's grants concentrate

Canada Pipeline Accessories Company, Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 50% of grants classified under G01F (Measuring Volume, Volume Flow, Mass Flow OR Liquid LEVEL; Metering BY Volume). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2022. By volume, Canada sits between Cqlt Saargummi Technologies S.À.R.L. and Carmel Pharma AB.

Canada's three-year grant acceleration

Canada Pipeline Accessories Company, Ltd. shows 4 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.
