Does more volume mean deeper claims for Dundee?

Each dot is one of Dundee’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). Dundee’s own 13.0 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 Dundee's grants concentrate

Dundee Sustainable Technologies Inc. is a focused PatentsView assignee: 8 CPC subclasses with 60% of grants classified under B09B (Disposal OF Solid Waste NOT Otherwise Provided FOR). By volume, Dundee sits between DU Pont-mitsui Fluorochemicals Co., Ltd. and Duran Group GMBH.

Dundee's three-year grant acceleration

Dundee Sustainable Technologies Inc. shows 1 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.
