What this shows Crushproof's Innovation Score is 44.8/100 (top 25% 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 Crushproof?

Each dot is one of Crushproof’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). Crushproof’s own 11.0 claims/patent is at or below the 18.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Crushproof's grants concentrate

Crushproof Tubing Co. is a focused PatentsView assignee: 9 CPC subclasses with 62.5% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2016. By volume, Crushproof sits between Crfs Limited and Cstone Pharmaceuticals.

Crushproof's three-year grant acceleration

Crushproof Tubing Co. shows 3 grants in 2022–2024 against only 0 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.
