What this shows Infrastructure's Innovation Score is 29.9/100 (32nd percentile 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 Infrastructure?

Each dot is one of Infrastructure’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). Infrastructure’s own 8.2 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Infrastructure's grants concentrate

Infrastructure Renewal Institute of Southern China is a focused PatentsView assignee: 8 CPC subclasses with 70% 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 2021 (5 grants) versus a trough of 1 in 2023. By volume, Infrastructure sits between Industry-University Cooperation Foundation Sunmoon University and Innovative Environmental Companies.

Infrastructure's three-year grant acceleration

Infrastructure Renewal Institute of Southern China shows 5 grants in 2022–2024 against only 5 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.
