What this shows QC'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 QC?
Each dot is one of QC’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). QC’s own 20.4 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where QC's grants concentrate
QC Manufacturing, Inc. is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under F24F (AIR-CONDITIONING; AIR-HUMIDIFICATION; VENTILATION; USE OF AIR Currents FOR Screening). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, QC sits between Protenus, Inc. and Rasirc, Inc..
QC's three-year grant acceleration
QC Manufacturing, Inc. shows 9 grants in 2022–2024 against only 7 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.
