What this shows Steelhead's Innovation Score is 29.9/100 (32nd 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 Steelhead?

Each dot is one of Steelhead’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). Steelhead’s own 15.0 claims/patent is ABOVE the 10.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Steelhead's grants concentrate

Steelhead Composites, Inc. is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under F17C (Vessels FOR Containing OR Storing Compressed, Liquefied OR Solidified GASES; Fixed-capacity GAS-HOLDERS; Filling Vessels With, OR Discharging From Vessels, Compressed, Liquefied, OR Solidified Gases). By volume, Steelhead sits between Stat Capsule Inc. and StimLabs LLC.

Steelhead's three-year grant acceleration

Steelhead Composites, Inc. shows 1 grants in 2022–2024 against only 1 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.
