What this shows Standex's Innovation Score is 43.9/100 (top 27% 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 Standex?

Each dot is one of Standex’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). Standex’s own 12.6 claims/patent is at or below the 17.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Standex's grants concentrate

Standex International Corporation is a focused PatentsView assignee: 38 CPC subclasses with 27.8% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2015. By volume, Standex sits between Specialty Granules Investments LLC and Stillwater Designs and Audio, Inc..

Standex's three-year grant acceleration

Standex International Corporation shows 4 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.
