What this shows Dukshin's Innovation Score is 40.0/100 (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 Dukshin?

Each dot is one of Dukshin’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). Dukshin’s own 2.5 claims/patent is at or below the 12.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dukshin's grants concentrate

Dukshin Corp., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 7.7% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2015. By volume, Dukshin sits between DR. Schneider Kunststoffwerke GMBH and Davis Intellectual Properties LLC.

Dukshin's three-year grant acceleration

Dukshin Corp., Ltd. shows 7 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.
