What this shows Brasscraft's Innovation Score is 35.5/100 (top 49% 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 Brasscraft?

Each dot is one of Brasscraft’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). Brasscraft’s own 12.4 claims/patent is at or below the 17.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Brasscraft's grants concentrate

Brasscraft Manufacturing Company is a focused PatentsView assignee: 13 CPC subclasses with 25% of grants classified under E03C (Domestic Plumbing Installations FOR Fresh Water OR Waste Water ; Sinks). Peak complete grant year is 2016 (21 grants) versus a trough of 1 in 2015. By volume, Brasscraft sits between Arrowhead Center, Inc. and Boomcloud 360 Inc..

Brasscraft's three-year grant acceleration

Brasscraft Manufacturing Company shows 3 grants in 2022–2024 against only 7 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.
