What this shows Blucher's Innovation Score is 20.1/100 (7th 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 Blucher?

Each dot is one of Blucher’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). Blucher’s own 2.2 claims/patent is at or below the 10.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Blucher's grants concentrate

Blucher Metal A/S is a focused PatentsView assignee: 3 CPC subclasses with 7.1% of grants classified under E04D (Roof COVERINGS; SKY-LIGHTS; GUTTERS; Roof-working Tools). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2022. By volume, Blucher sits between Bidi Vapor, LLC and Borgwarner Beru Systems GMBH.

Blucher's three-year grant acceleration

Blucher Metal A/S shows 1 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.
