What this shows Rt-filtertechnik's Innovation Score is 28.9/100 (29th 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 Rt-filtertechnik?

Each dot is one of Rt-filtertechnik’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). Rt-filtertechnik’s own 15.0 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Rt-filtertechnik's grants concentrate

Rt-filtertechnik GMBH is a focused PatentsView assignee: 3 CPC subclasses with 93.3% of grants classified under B01D (Separation). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2017. By volume, Rt-filtertechnik sits between Rofin-sinar Technologies LLC and Rwth Aachen.

Rt-filtertechnik's three-year grant acceleration

Rt-filtertechnik GMBH shows 5 grants in 2022–2024 against only 8 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.
