What this shows Carnival's Innovation Score is 39.2/100 (top 39% 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 Carnival?

Each dot is one of Carnival’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). Carnival’s own 14.7 claims/patent is ABOVE the 12.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Carnival's grants concentrate

Carnival Corporation is a focused PatentsView assignee: 5 CPC subclasses with 76.9% of grants classified under H04B (Transmission). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2022. By volume, Carnival sits between Calsonic Kansei North America, Inc. and Center FOR Advanced Soft Electronics.

Carnival's three-year grant acceleration

Carnival Corporation shows 4 grants in 2022–2024 against only 2 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.
