What this shows Qinterra's Innovation Score is 28.2/100 (26th percentile 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 Qinterra?

Each dot is one of Qinterra’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). Qinterra’s own 14.4 claims/patent is at or below the 15.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Qinterra's grants concentrate

Qinterra Technologies AS is a focused PatentsView assignee: 6 CPC subclasses with 100% 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 2020 (7 grants) versus a trough of 1 in 2017. By volume, Qinterra sits between Qiaokang Biotech (GUANGDONG) Co., Ltd. and Ranovus Inc..

Qinterra's three-year grant acceleration

Qinterra Technologies AS shows 2 grants in 2022–2024 against only 12 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.
