What this shows Cleantek's Innovation Score is 53.9/100 (top 8% 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 Cleantek?

Each dot is one of Cleantek’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). Cleantek’s own 15.6 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cleantek's grants concentrate

Cleantek Industries Inc. is a focused PatentsView assignee: 23 CPC subclasses with 50% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). By volume, Cleantek sits between Cisbio Bioassays and Clinical Genomics PTY Ltd.

Cleantek's three-year grant acceleration

Cleantek Industries Inc. shows 6 grants in 2022–2024 against only 2 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.
