What this shows Louisiana's Innovation Score is 48.3/100 (top 17% 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 Louisiana?

Each dot is one of Louisiana’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). Louisiana’s own 17.1 claims/patent is ABOVE the 14.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Louisiana's grants concentrate

Louisiana Tech Research Corporation is a focused PatentsView assignee: 49 CPC subclasses with 20% of grants classified under C04B (Lime, MAGNESIA; SLAG; CEMENTS; Compositions Thereof, e.g. Mortars, Concrete OR Like Building MATERIALS; Artificial Stone ; Ceramics ; REFRACTORIES; Treatment OF Natural Stone). Peak complete grant year is 2016 (5 grants) versus a trough of 1 in 2015. By volume, Louisiana sits between Liqxtal Technology Inc. and Leibniz-Institut für Neue Materialien gemeinnützige GmbH.

Louisiana's three-year grant acceleration

Louisiana Tech Research Corporation shows 3 grants in 2022–2024 against only 10 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.
