What this shows Sino's Innovation Score is 41.6/100 (top 33% 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 Sino?

Each dot is one of Sino’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). Sino’s own 13.0 claims/patent is at or below the 14.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Sino's grants concentrate

Sino Canada Health Engineering Research Institute (HEFEI) Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 83.3% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2021. By volume, Sino sits between Sinclair Television Group, Inc and Sinopec Southwest OIL & GAS Company.

Sino's three-year grant acceleration

Sino Canada Health Engineering Research Institute (HEFEI) Ltd. shows 4 grants in 2022–2024 against only 1 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.
