What this shows Rolf's Innovation Score is 31.4/100 (38th 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 Rolf?

Each dot is one of Rolf’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). Rolf’s own 9.7 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 Rolf's grants concentrate

Rolf C. Hagen Inc. is a focused PatentsView assignee: 2 CPC subclasses with 42.9% of grants classified under A01K (Animal HUSBANDRY; AVICULTURE; APICULTURE; PISCICULTURE; FISHING; Rearing OR Breeding Animals, NOT Otherwise Provided FOR; NEW Breeds OF Animals). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2016. By volume, Rolf sits between Rocket Fuel Inc. and Ross Power Investments Inc..

Rolf's three-year grant acceleration

Rolf C. Hagen Inc. shows 4 grants in 2022–2024 against only 2 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.
