What this shows Lontra's Innovation Score is 39.4/100 (top 38% 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.

Where Lontra's grants concentrate

Lontra Limited is a focused PatentsView assignee: 12 CPC subclasses with 85.7% of grants classified under F01C (Rotary-piston OR Oscillating-piston Machines OR Engines). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, Lontra sits between Locl Pharma, Inc. and Luft Industrie Inc..

Lontra's three-year grant acceleration

Lontra Limited shows 6 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.
