What this shows Oil-rite's Innovation Score is 25.5/100 (17th 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 Oil-rite?

Each dot is one of Oil-rite’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). Oil-rite’s own 13.4 claims/patent is ABOVE the 12.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Oil-rite's grants concentrate

Oil-rite Corporation is a focused PatentsView assignee: 5 CPC subclasses with 60% of grants classified under G01F (Measuring Volume, Volume Flow, Mass Flow OR Liquid LEVEL; Metering BY Volume). By volume, Oil-rite sits between OFS Brands Inc. and Omega Life Science Ltd..

Oil-rite's three-year grant acceleration

Oil-rite Corporation shows 1 grants in 2022–2024 against only 2 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.
