What this shows Tennant's Innovation Score is 44.9/100 (top 25% 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 Tennant?

Each dot is one of Tennant’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). Tennant’s own 16.2 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Tennant's grants concentrate

Tennant Company is a focused PatentsView assignee: 33 CPC subclasses with 66.7% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2015 (12 grants) versus a trough of 1 in 2022. By volume, Tennant sits between Spinal Simplicity, LLC and TetraMem Inc..

Tennant's three-year grant acceleration

Tennant Company shows 4 grants in 2022–2024 against only 17 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.
