What this shows Q.e.d.'s Innovation Score is 54.0/100 (top 8% 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 Q.e.d.?

Each dot is one of Q.e.d.’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). Q.e.d.’s own 16.6 claims/patent is at or below the 18.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Q.e.d.'s grants concentrate

Q.E.D. Environmental Systems, Inc. is a focused PatentsView assignee: 19 CPC subclasses with 54.5% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2018 (6 grants) versus a trough of 1 in 2020. By volume, Q.e.d. sits between Protiva Biotherapeutics, Inc. and QuantaEd, LLC.

Q.e.d.'s three-year grant acceleration

Q.E.D. Environmental Systems, Inc. shows 8 grants in 2022–2024 against only 3 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.
