What this shows Mirka's Innovation Score is 50.6/100 (top 13% 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 Mirka?

Each dot is one of Mirka’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). Mirka’s own 8.8 claims/patent is at or below the 16.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mirka's grants concentrate

Mirka Ltd is a focused PatentsView assignee: 15 CPC subclasses with 28.6% of grants classified under B24D (Tools FOR Grinding, Buffing OR Sharpening). Peak complete grant year is 2024 (9 grants) versus a trough of 1 in 2020. By volume, Mirka sits between Measurement Incorporated and National Christmas Products LLC.

Mirka's three-year grant acceleration

Mirka Ltd shows 15 grants in 2022–2024 against only 3 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.
