What this shows Hach's Innovation Score is 34.1/100 (47th 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 Hach?

Each dot is one of Hach’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). Hach’s own 11.8 claims/patent is at or below the 11.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hach's grants concentrate

Hach Lange GMBH is a focused PatentsView assignee: 13 CPC subclasses with 86.1% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2024. By volume, Hach sits between Georg Fischer Rohrleitungssysteme AG and Hopto Inc..

Hach's three-year grant acceleration

Hach Lange GMBH shows 3 grants in 2022–2024 against only 11 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.
