What this shows Spears's Innovation Score is 46.6/100 (top 20% 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 Spears?

Each dot is one of Spears’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). Spears’s own 15.7 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spears's grants concentrate

Spears Manufacturing Co. is a focused PatentsView assignee: 10 CPC subclasses with 85.7% 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 2017 (5 grants) versus a trough of 1 in 2015. By volume, Spears sits between SolarWindow Technologies, Inc. and Star Sky Motor.

Spears's three-year grant acceleration

Spears Manufacturing Co. shows 5 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.
