What this shows Checkmate's Innovation Score is 25.4/100 (17th 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 Checkmate?

Each dot is one of Checkmate’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). Checkmate’s own 5.5 claims/patent is at or below the 10.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Checkmate's grants concentrate

Checkmate Lifting & Safety Ltd is a focused PatentsView assignee: 4 CPC subclasses with 14.3% of grants classified under A62B (Devices, Apparatus OR Methods FOR Life-saving). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2018. By volume, Checkmate sits between Cellresearch Corporation PTE. Ltd. and City Labs, Inc..

Checkmate's three-year grant acceleration

Checkmate Lifting & Safety Ltd shows 6 grants in 2022–2024 against only 7 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.
