What this shows Testo's Innovation Score is 41.8/100 (top 32% 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 Testo?

Each dot is one of Testo’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). Testo’s own 15.9 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Testo's grants concentrate

Testo SE & Co. KGaA is a focused PatentsView assignee: 17 CPC subclasses with 72.2% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2019. By volume, Testo sits between Tenaris Connections B.V. and The Bradbury Co., Inc..

Testo's three-year grant acceleration

Testo SE & Co. KGaA shows 9 grants in 2022–2024 against only 8 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.
