What this shows Rumfert's Innovation Score is 43.8/100 (top 27% 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 Rumfert?

Each dot is one of Rumfert’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). Rumfert’s own 18.4 claims/patent is at or below the 19.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rumfert's grants concentrate

Rumfert, LLC is a focused PatentsView assignee: 12 CPC subclasses with 71.4% of grants classified under G08G (Traffic Control Systems). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2019. By volume, Rumfert sits between RPC Superfos A/S and Raimund Beck Nageltechnik GmbH.

Rumfert's three-year grant acceleration

Rumfert, LLC 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.
