What this shows Fontaine's Innovation Score is 27.3/100 (23rd 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 Fontaine?

Each dot is one of Fontaine’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). Fontaine’s own 7.3 claims/patent is at or below the 18.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Fontaine's grants concentrate

Fontaine Engineering und Maschinen GmbH is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under C23C (Coating Metallic MATERIAL; Coating Material With Metallic MATERIAL; Surface Treatment OF Metallic Material BY Diffusion Into THE Surface, BY Chemical Conversion OR SUBSTITUTION; Coating BY Vacuum Evap). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2022. By volume, Fontaine sits between Flying Whales and Food Cycle Science Corporation.

Fontaine's three-year grant acceleration

Fontaine Engineering und Maschinen GmbH shows 4 grants in 2022–2024 against only 4 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.
