What this shows Qualitrol's Innovation Score is 45.7/100 (top 23% 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 Qualitrol?

Each dot is one of Qualitrol’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). Qualitrol’s own 20.7 claims/patent is ABOVE the 16.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Qualitrol's grants concentrate

Qualitrol Company LLC is a focused PatentsView assignee: 13 CPC subclasses with 42.9% of grants classified under G01R (Measuring Electric VARIABLES; Measuring Magnetic Variables). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2018. By volume, Qualitrol sits between QorTek, Inc. and Quantum Elctro Opto Systems Sdn Bhd..

Qualitrol's three-year grant acceleration

Qualitrol Company LLC shows 2 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.
