What this shows Freudenberg's Innovation Score is 28.8/100 (28th 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 Freudenberg?

Each dot is one of Freudenberg’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). Freudenberg’s own 14.6 claims/patent is ABOVE the 10.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Freudenberg's grants concentrate

Freudenberg Sealing Technologies S.A.S. DI Externa Italia S.R.L.U. is a focused PatentsView assignee: 6 CPC subclasses with 69.2% of grants classified under F16J (Pistons ; CYLINDERS; Sealings). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, Freudenberg sits between Fluid Metering, Inc. and Fundacio Institut DE Recerca Biomedica (IRB BARCELONA).

Freudenberg's three-year grant acceleration

Freudenberg Sealing Technologies S.A.S. DI Externa Italia S.R.L.U. shows 2 grants in 2022–2024 against only 6 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.
