What this shows CM's Innovation Score is 37.1/100 (top 44% 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 CM?

Each dot is one of CM’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). CM’s own 19.3 claims/patent is ABOVE the 9.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where CM's grants concentrate

CM HK Limited is a focused PatentsView assignee: 12 CPC subclasses with 57.9% of grants classified under G01C (Measuring Distances, Levels OR BEARINGS; SURVEYING; NAVIGATION; Gyroscopic INSTRUMENTS; Photogrammetry OR Videogrammetry). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2019. By volume, CM sits between Chronos Tech LLC and Compass Plants B.V..

CM's three-year grant acceleration

CM HK Limited shows 4 grants in 2022–2024 against only 9 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.
