What this shows Caillau's Innovation Score is 40.4/100 (top 36% 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 Caillau's grants concentrate

Caillau is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under F16L (PIPES; Joints OR Fittings FOR PIPES; Supports FOR Pipes, Cables OR Protective TUBING; Means FOR Thermal Insulation IN General). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2021. By volume, Caillau sits between Cytoaurora Biotechnologies, Inc. and Calibo LLC.

Caillau's three-year grant acceleration

Caillau shows 4 grants in 2022–2024 against only 1 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.
