What this shows Oxis's Innovation Score is 31.9/100 (39th 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 Oxis?

Each dot is one of Oxis’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). Oxis’s own 14.2 claims/patent is ABOVE the 13.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Oxis's grants concentrate

Oxis Energy Limited is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2019. By volume, Oxis sits between Oriental Motor Co., Ltd. and Obeebo Labs Ltd..

Oxis's three-year grant acceleration

Oxis Energy Limited shows 2 grants in 2022–2024 against only 5 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.
