What this shows Opex's Innovation Score is 56.2/100 (top 6% 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 Opex?

Each dot is one of Opex’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). Opex’s own 18.6 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Opex's grants concentrate

Opex Corporation is a focused PatentsView assignee: 17 CPC subclasses with 71.1% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2024 (19 grants) versus a trough of 1 in 2016. By volume, Opex sits between Meiji Seika Pharma Co., Ltd. and Samson Aktiengesellschaft.

Opex's three-year grant acceleration

Opex Corporation shows 44 grants in 2022–2024 against only 19 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.
