What this shows Doben's Innovation Score is 50.8/100 (top 12% 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 Doben?

Each dot is one of Doben’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). Doben’s own 16.6 claims/patent is ABOVE the 8.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Doben's grants concentrate

Doben Limited is a focused PatentsView assignee: 11 CPC subclasses with 61.5% of grants classified under B23K (Soldering OR UNSOLDERING; WELDING; Cladding OR Plating BY Soldering OR WELDING; Cutting BY Applying Heat Locally, e.g. Flame CUTTING; Working BY Laser Beam). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Doben sits between Dh2i Company and DR. Schneider Kunststoffwerke GMBH.

Doben's three-year grant acceleration

Doben Limited shows 4 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.
