What this shows Spencer's Innovation Score is 36.0/100 (top 48% 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 Spencer?

Each dot is one of Spencer’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). Spencer’s own 16.9 claims/patent is at or below the 19.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Spencer's grants concentrate

Spencer Composites Corporation is a focused PatentsView assignee: 17 CPC subclasses with 66.7% 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). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, Spencer sits between Specifio, Inc. and Splash About International Limited.

Spencer's three-year grant acceleration

Spencer Composites Corporation shows 2 grants in 2022–2024 against only 4 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.
