What this shows Quartus's Innovation Score is 51.3/100 (top 12% 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 Quartus?

Each dot is one of Quartus’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). Quartus’s own 23.3 claims/patent is ABOVE the 11.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quartus's grants concentrate

Quartus Engineering Incorporated is a focused PatentsView assignee: 7 CPC subclasses with 44.4% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2024 (2 grants) versus a trough of 1 in 2016. By volume, Quartus sits between Quality Craft Industries, Inc. and Quintel Technology Limited.

Quartus's three-year grant acceleration

Quartus Engineering Incorporated shows 3 grants in 2022–2024 against only 0 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.
