What this shows Mack-ray's Innovation Score is 21.8/100 (9th 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 Mack-ray?

Each dot is one of Mack-ray’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). Mack-ray’s own 15.5 claims/patent is at or below the 17.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mack-ray's grants concentrate

Mack-Ray Inc. is a focused PatentsView assignee: 1 CPC subclasses with 75% of grants classified under B26B (Hand-held Cutting Tools NOT Otherwise Provided FOR). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2018. By volume, Mack-ray sits between Mylaps B.V. and Magna Car Top Systems GmbH.

Mack-ray's three-year grant acceleration

Mack-Ray Inc. shows 1 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.
