What this shows Cairn5's Innovation Score is 39.9/100 (top 37% 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 Cairn5?

Each dot is one of Cairn5’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). Cairn5’s own 22.2 claims/patent is ABOVE the 17.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Cairn5's grants concentrate

Cairn5 LLC is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). By volume, Cairn5 sits between Caddo Medical Technologies LLC and Calico Life Sciences LLC.

Cairn5's three-year grant acceleration

Cairn5 LLC shows 2 grants in 2022–2024 against only 0 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.
