What this shows AOI's Innovation Score is 37.4/100 (top 44% 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 AOI?

Each dot is one of AOI’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). AOI’s own 27.3 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where AOI's grants concentrate

AOI (Advanced Oilfield Innovations, Inc.) is a focused PatentsView assignee: 15 CPC subclasses with 62.5% 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 2020 (3 grants) versus a trough of 1 in 2018. By volume, AOI sits between Ankobot (SHENZHEN) Smart Technologies Co., Ltd. and APL Norway AS.

AOI's three-year grant acceleration

AOI (Advanced Oilfield Innovations, Inc.) shows 1 grants in 2022–2024 against only 6 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.
