What this shows Mintek's Innovation Score is 26.0/100 (19th 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 Mintek?

Each dot is one of Mintek’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). Mintek’s own 9.0 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Mintek's grants concentrate

Mintek is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under C02F (Treatment OF Water, Waste Water, Sewage, OR Sludge). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2017. By volume, Mintek sits between Milspray LLC and Mitsubishi Electric Building Solutions Corporation.

Mintek's three-year grant acceleration

Mintek shows 1 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.
