What this shows Oxford's Innovation Score is 42.7/100 (top 30% 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 Oxford?

Each dot is one of Oxford’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). Oxford’s own 11.3 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Oxford's grants concentrate

Oxford Photovoltaics Limited is a focused PatentsView assignee: 14 CPC subclasses with 60.9% of grants classified under Y02E (Reduction OF Greenhouse GAS [GHG] Emissions, Related TO Energy Generation, Transmission OR Distribution). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2018. By volume, Oxford sits between Omega Patents, L.L.C. and Opus IVS, Inc..

Oxford's three-year grant acceleration

Oxford Photovoltaics Limited shows 7 grants in 2022–2024 against only 4 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.
