What this shows Dart's Innovation Score is 46.0/100 (top 22% 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 Dart?

Each dot is one of Dart’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). Dart’s own 22.5 claims/patent is ABOVE the 15.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dart's grants concentrate

Dart Container Corporation is a focused PatentsView assignee: 16 CPC subclasses with 57.1% of grants classified under B65D (Containers FOR Storage OR Transport OF Articles OR Materials, e.g. Bags, Barrels, Bottles, Boxes, Cans, Cartons, Crates, Drums, Jars, Tanks, Hoppers, Forwarding CONTAINERS; Accessories, Closures, OR F). Peak complete grant year is 2016 (6 grants) versus a trough of 1 in 2015. By volume, Dart sits between Danfoss Silicon Power GMBH and Equashield Medical Ltd.

Dart's three-year grant acceleration

Dart Container Corporation shows 8 grants in 2022–2024 against only 9 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.
